Title: What's the best registry cleaner? Ask Leo says: none
Post by: mouser on July 03, 2006, 12:58 AM
we've actually discussed this before.. and i tend to come to the same conclusion, mostly because the risk of deleting something important seems so high to me, i'd rather not take the chance..

What would be the best software to buy to fix and clean the registry for Windows XP Professional?

There's a wide variety of opinion on registry cleaners. Many people believe that they're important tools to keep your system running smoothly.

My opinion's a little different.

I rarely use a registry cleaner. In fact, I've never actually felt that I've needed to use a registry cleaner. And I definitely install and play with random things on my machine on a regular basis.

My fundamental belief is that the best registry cleaner is no registry cleaner at all. Most people simply don't need it, and don't need to run one.

The best registry cleaner is using applications that don't use the registry, but config or ini files instead.

Eventhough Microsoft hates this, and is secretly trying to get rid of ini files.

(Who's Leo? Never saw that site. There seems to be mostly very basic stuff on there. I don't think it's a good idea to scare new users into not-fiddling-with-their-computer... after all,... how else are they going to learn stuff? ;) )

Most registry cleaner are unsafe to use for new users. I agree with mouser that there is a high risk of deleting something important. A few years ago I used a registry cleaner tool on Windows ME and it broke the OS, I have to reinstall the whole OS. I am still using a old and safe cleaner program call RegCleaner which is a freeware but no longer supported, so far no problem with it. There are also some free registry defragment and compression software that are safe to use, however avoid registry cleaner. Of course, it is important that you backup your registry and turn on system restore so that old copies of the registries can be restored.

Id hate to think of a third party app fiddling with my reg, especially with some of these apps doing the change without showing what its done. But i loved X-Setup from xteq (http://www.xteq.com) (i say loved, i used it before it went all pro because i pretty much knowall the keys and subkeys from over the years and didn`t really need it anymore). It a fine app , i think the pre-pro version is still avalailabe for free somewhere.

I really liked it because it was a manual process, it was in depth on what you where actually changing and it could do it in a non-destructive way as it could save the history ( that is if you didn`t totally screw up the settings and could still get your machine to boot). Oh, and it allowed you to create some really usefull scripts to share with other users.

Admitidly it wasn`t a automated registry cleaner (of course it had scripts that checked for orphaned keys and such, which basically is just what most automated cleaners do) which is can only be a good thing, as quite frankly if you dont know how to manually control the registry you shouldnt really be messing around with it. At least if your fiddling with your reg with x-setup , the interface was very intuitive and could in some instances really stop tears before bedtime.

Two previous threads have covered this at length:

https://www.donationcoder.com/forum/index.php?topic=1188.0
https://www.donationcoder.com/forum/index.php?topic=2964.0

I still say the best cleaner in no cleaner.

I am using CrapCleaner on my system and have jv16 PowerTools 2006 installed.

jv16 is one of the highest rated registry cleaners out there (and has been for years) garnering the support of people like Fred Langa but ....

I have run both to see what 'problems' they come up with and both come up with a lot that on closer inspection would delete many vital keys if just run automatically. Both also delete all placeholders used by MS in their Office products (keys that don't point anywhere or to a non-existent file that will be added only if you you need it - either from the installation media or the web) and quite a few empty references for other installed apps.

You could argue that empty keys are a waste of space but I presume they are there for a purpose - just because registry cleaners (and me) don't know why it isn't a good excuse to simply delete them.

People who recommend reg cleaners rarely suggest running them in automatic mode (in fact anyone who does that is totally mad). The trouble is what do you do manually when you are confronted by about 1500 anomalies - many of which don't have any obvious function, or are so obfuscated as to be unfixable manually ?

I do run the two I recommend above in "strictly" manual mode - deleting only green items in Regseeker,  rechecking each key manually in Regvac, so .....I must be partially sane <grin>

If you're referring to the MS tool that has an icon of a cyan box with a red ribbon on it, that tool is not safe.

I haven't really noticed any cases where a registry cleaner caused any noticeable speed effect; the registry is stored in a binary and pretty efficient format. Looking up keys/values uses a binary search, which means that to find a key out of 4.294.967.296 takes a maximum of log(2**32)/log(2) compares - that's 32 compares. Of course most registries have a lot less entries than that, so it's even faster.

One thing that DOES help, though, is to keep your registry defragmented..

Since the best registry cleaners have a backup option, there's no problems if you delete a critical setting in the registry, restore the backup and it's done. I'll endorse PowerTools since I've been using software developed by Jouni Vuorio, the head of Macecraft since 2000, when I got my computer. No problems so far in all those 6 years, not even with MS Office 2000 installed.

Please don't use RegCleaner of Microsoft's RegClean. They're both old, and they could give serious problems with newer computers and software. I tried the last version of RegCleaner months ago, and the program showed some entries in the registry which were dangerous to delete according to my own experience.

Don't use RegSeeker as well. It's very very aggressive and it shows a great deal of entries that could give some problems if deleted. Not to mention the algorithms used to detect useless entries need some rewriting, as it can't detect real paths properly.

EasyCleaner seems like a good option for those using freeware, now if the GUI wasn't so awful... I also use the registry cleaner included in TuneUp Utilities, which complements PowerTools perfectly, and it's also very good, especially for the CLSID entries.

And finally, Mr. Langa could update its comparison to include some other recent registry cleaners like TweakNow's offer (it's not that good, but anyway) and the AMUST Registry Cleaner, which I really don't know if it works or not, since it's only for Win2K and up, but seems like a decent choice.

I have used Fix It Utilities registry fixer for several years on different laptops and never had any problems, provided that you remove only those recommended by default (and I never tried to delete any others). :up:

I have recently been using the trial version of jv16 Power Tools.  When it finishes scanning, I have been choosing "Select all" and then "Fix".  I find that jv16 PT comes up with a much longer list of items to delete.  SO far have not had any problems. :up:

I have always run them in the manual mode.

The bigger and more important question that I cannot answer is how much better or worse things would be if I had not flushed them to begin with. :-\
Title: Re: What's the best registry cleaner? Ask Leo says: none
Post by: Carol Haynes on July 20, 2006, 08:59 AM
"Select All" > "Fix" is not manual mode - that is automatic mode. Expect some problems!

I have found things look good for a while and then you start to notice odd little things and irritations start to happen. Because the computer doesn't burst into flames when you click fix does not mean everything is alright - trouble is by the time you start noticing the problems you forget that little button you clicked!

Best solution is to make a windows recovery disc (including a registry image) before undertaking any major registry surgery.

You can do that from Windows Backup (see Start > Accessories > System Tools > Backup) on the "Welcome" tab hit Automated System Recovery Wizard (in the WinXP version anyway). You will need a blank floppy.

If you trash your system you can use the Windows repair function by booting from the original windows CD.

m...I might be the few who still think registry cleaner is safe, especially commercial version!
Some free version is good, but many is not up to date or might be obsolete in the near future.

I must admit during the time when Windows XP first launching, registry cleaner is very rare and many done harm then good.

But from my experience, I must say that nowsaday paid registry cleaner is very safe!

For free registry cleaners, I would recommend
EUsing => http://www.eusing.com/free_registry_cleaner/registry_cleaner.htm
CCleaner =>http://www.ccleaner.com/
Regseeker =>http://www.hoverdesk.net/freeware.htm

If you still concern about The Danger of Registry Cleaner => http://www.review-registry-cleaner.com/comp-problem/the-danger-of-registry-cleaner/

I personally use 3 free cleaners and 2 paid cleaners, many windows problems can be easily fixed =>http://www.review-registry-cleaner.com/category/comp-problem/

But in the near future, Microsoft will 100% fix it with .NET platform! becuase dot net is using XML to store configuration instead of registry. Until then we still need registry cleaners, many good stuff out there...

No single 1 registry cleaners can detect and clean all errors.

I have tested 10 registry cleaners, even thought I cleaner with each of them, there are still errors to be found!

My conclusion is: No single registry cleaner can clean all errors.

I also agree that most registry cleaners are not as useful as expected - also combinations do not deliver satisfying results, I think.

If you take a close look what Registry-Cleaners are doing you´ll see that only some very special branches are "cleaned". GUIDs and spreaded informations of some programs/dlls/paths/Setup-Collections are not searched/found perfectly. With each hardware/software you install or connect the registry is growing more and more with informations you´ll never be able to clean automatically in a perfect way.

I sometimes let a cleaner run over it (just for fun), but the best results I get by hand. I must admit that in the beginning I killed too much entries but with the time the knowledge what to delete and what you mustn´t is growing. This "knowledge" should be included in these registry-cleaners as some kind of artificial intelligence to decide what level can be delete and what connections perhaps belong to other branches - and this seems to be too complicate. So they use the simpliest ways to decide what has to be deleted and throw their tools on the market - doing only half of the job that could possibly be done.

Only rather few entries in the Software-branch makes it possible to slowdown every registry-search/installation/deinstallation, the Startup-List and right-mouse-button-command-list.

Why?

The problem is that microsoft never intended to let so much programs install and write mostly useless shit cross-seeded in the registry. They never thought someone could use a running computer for more than two or three years without reinstalling or upgrading the operating system. It was easier for programmers to write/create some keys in the registry and not to use ini-files. This can also be done quite simple - but the registry functions are a perfect container for "hidden" informations that can not be changed as easily by normal users. If I could make a decision for further Windows-Versions I would ban the registry for anything else than the OS itself and force the programmers to split their informations in seperate and easy to clean/manage ini-files or at least reorganize the structure of the registry itself.

The best thing would be a combination with a virtualization-system like Altiris SVS that can split/bypass all informations of a program in a separate folder. If it only would do this with registry entries (it does this with every single file created by a virtualization layer ... this is good for temporary/testing purposes, but not for a simple registry-splitting) this could be a perfect solution/addon for the registry! There are some other flaws in this prog, but the direction seems to be the right one!

Josh => Yes, I am the webmaster...
Crush => Can't agree more! But manually remove is a tedious task, takes some time and some technical knowledge. The biggest problem with Windows registry is the tree structure, and many software design to "full explore" this function with each every information, configuration all stored into the registry, and the only result is slowing down the system.

Hopefully .Net application don't do that anymore...! I see some .net application still access to registry for some reasons, still a long way before all changed to dot net.

I use jv16 Powertools 2007 for registry cleaning. I don't use it in any kind of Automatic Mode; instead I monitor each cleaning and only select those keys which I recognize as being associated with items I feel comfortable with.  It is configured to create a backup of all affected keys, plus I backup the entire registry weekly.

There are many cases I have seen where certain applications I once had installed still have a lot of keys that are no longer beneficial.

Also, Acronis images help me feel a bit safer.

I've been running these on my system for years, right before I backup the system.

1. TuneUp Registry Cleaner (http://www.tune-up.com/products/tuneup-utilities/)
2. PC Tools Registry Mechanic (http://www.pctools.com/registry-mechanic/)
3. TuneUp RegistryDefrag (http://www.tune-up.com/products/tuneup-utilities/)

The only problem I had was Registry Mechanic deleting my HijackThis 'ignored apps' list - I asked Registry Mechanic to ignore that specific key and haven't had a problem since. I doubt if I'd have run these if I didn't have previous system backups to rely on though.

I do the same, you should get Acronis True Image for backup, I use this tools for 3 years and recently join them as affiliate as well.

Direct link is here =>http://www.acronis.com/
Affiliate link is here => <a href="http://www.review-registry-cleaner.com/products/trueimage/"> Acronis True Image </a>

I have tried Newer version of Acronis True Image (I didn't upgrade, still using version 10), they have a very cool features called Try&Decide. When activated you can try anything on your computer including registry repair, you can try to corrupt your windows and Acronis True Image will record every action you take on your drive.

After testing, you can easily restore it to previous stat. But I still prefer to backup manually before using this Try&Decide feature (Only available in version 11).

Please don't take my word for it, try for yourself. I only share the best I used, there are still many best thing out there...

-supertechnogeek (December 25, 2007, 08:27 PM)
That's bull. Registry lookups are very efficient since binary search is used for looking up keys; this basically means that the number of keys has to double for one extra compare instruction to be necessary.

Oh, and when you're an affiliate or have any form of connection with a product you're posting about, you should state this very clearly in the post. Nobody here likes hidden agendas.

Another vote for Regseeker from me. I've tried using jv16 Power Tools in the past, but while its a good program, its risky and deletes several important registry keys. Well, its screwed up my PC before. I've also used the registry cleaner on WinXP Manager, which is likewise, very powerful, but risky. The best method is to use applications that can simply be unarchived and run and only create .ini files. Thinstall applications are also another option, but Thinstall costs a lot of money. Other good registry cleaners I've come across include EasyCleaner and CCleaner's Registry Clean Function.

I've heard many tech site authors strongly recommend registry mechanic. I tried the demo, but did not find it to be all that impressive for a shareware application. Any other dc users tried it?

I did try registry mechanic, but a long time ago. I think it was good... or was it ? But how shall I really be able to tell ?
Actually, like some here, I stopped using registry cleaners (and in facts most cleaners, registry or not!) after experiencing problems related to these, sometimes weeks or even months after cleaning my machine.

There were a couple of times where some software problems were actually instantly solved by cleaning the registry with TuneUp Utilities registry cleaner  (the only one that actually never did anything wrong to my machine -- but I've stopped using it anyway... +  it's outdated...) (can't remember exactly what the problem was... it was at least 2-3 years ago).

I'm another very happy user of JV PowerTools Registry Cleaner.  I've used it for years, always in "Normal" (as opposed to "Aggressive") mode.  I've almost always told it to fix everything it has identified, and I've always had it make a backup.  Frankly, it has never removed anything I later found I needed (knock on wood  :) ).  The only other registry cleaner I've ever tried was the one in Advanced Windows Care Professional.  I used it only once.  I first ran JV PowerTools, and it found about 70 registry entries to fix or remove.  I then ran the registry cleaner in Advanced Windows Care Professional.  It found more than 900 additional entries.  That made me uncomfortable, not with JV PowerTools but with AWC.  My guess is that AWC was taking a much more aggressive approach, one that JV PowerTools offers but cautions about.  I've never found that approach necessary, and I prefer to err on the side of caution.

I sound like a broken watch but registry cleaners are pointless and dangerous. So you have a few out of date entries knocking about (so what) and you probably have hundreds of unused entries installed by common applications such as Windows and Office (to name only two) that deliberately insert empty registry keys that are only filled when you download a particular plugin or what ever.

Just because you don't perceive immediate problems doesn't mean they don't appear down the line. The main problem is that by the time you have a problem you don't even think to blame the registry cleaner.

I am not saying MS is perfect (I know they are not) but if you have a few minutes to spare try installing in VirtualPC Windows Vista or XP clean install (you don't need to activate it) and an MS Office product. Then run any of the registry cleaners and look at how many 'errors' exist on a newly installed system. Many cleaners will literally find hundreds.

I used to use JV Powertools but gave up after I noticed that in a multiboot system it was 'fixing' registry problems in automatic mode with files on the wrong partition (i.e. a different version of windows altogether).

Apparently individual mileage will vary with this sort of utility. I've used Fix-it Utilities and Glary Utilities for several years now, and I have yet (knock wood) to experience the problems Carol has run into. On more than one occasion, Fix-It has succeeded in correcting some annoying issues that would otherwise have required large amounts of research (or a system reinstall) to correct.

Of course, there's always some risk when you mess with the Registry - even if you know what you're doing. So it's probably best to match your tools to your level of knowledge. And when in doubt - don't. :)

Moi aussi! I think in the hands of someone who knows what s/he is doing and who takes the time to consider each change suggested by a registry cleaner, a registry cleaner may not do any harm and may even do some good in cleaning up after naughtly uninstallers. However, for the vast majority of people (myself included), who do not take the time to go through all of the suggested changes to vet them before letting a registry cleaner "do its thing", I suggest following Brave Sir Robin (http://www.youtube.com/watch?v=BZwuTo7zKM8)'s example:

Brave Sir Robin ran away.
Bravely ran away, away!
When danger reared its ugly head,
He bravely turned his tail and fled.
Yes, brave Sir Robin turned about
And gallantly he chickened out.
Bravely taking to his feet
He beat a very brave retreat,
Bravest of the brave, Sir Robin!

He is packing it in and packing it up
And sneaking away and buggering up
And chickening out and pissing off home,
Yes, bravely he is throwing in the sponge...

here's the home page-

http://www.vitsoft.org.ua/index.htm

i've used (and still do) regseeker, glary, ccleaner and atf cleaner, cleanup! and atf as well as cleanup! has nothing to do with the registry-just threw them in

anyway I use the cleaner for files in ccleaner mainly for saving cookies i don't want deleted, so on the other cleaners i skip the cookies

since i've been using Vit, the other registry cleaners don't find much.

But watch out for the other cleaners in Vit, they are powerful. too powerful with a novice. Perhaps the reg cleaner part also.
But it does show exactly what it will do before you click 'Fix'.
With options to uncheck fixing anything.

Just to add to my earlier comment - my problem with registry cleaners in general is that there are more often than not FAR too many fixes suggested for me to go through carefully to critically evaluate whether or not I agree with them. Thus, the danger is very real that I'll bork my system unintentionally... Thus, my "response" to cmpm's note above is to reiterate and add to what I said in my previous post:

Be damned sure you back up your registry before making any changes to your registry and most important check each suggested change before letting a registry cleaner make changes to your system.

Overall, I've found it far easier to simply leave my registry alone. With XP and now Vista, just like RAM cleaners and pagefile tweaking I no longer see the need...

Just my two bits.

Darwin: yup, too overzealous, and "cleaning" the registry means just about nothing wrt. performance anyway (defragging is what matters).

Wrt. pagefile, 'tweaking' the size is more or less useless, and the various "1.5x system memory", "no! 2x system memory!" etc. is silly. Either you get enough RAM to turn it off completely, or you set a bigger-than-ever-needed minimum size (to avoid ever having to grow, possibly resulting in fragmentation). If you feel you do need a pagefile, it can help moving it to "the physical disk with the least traffic" (which might very well be your system disk - the blind advise of "don't put pagefile on your system disk" is as silly as anything).

It's true that most keys found in a good registry clean don't matter much. They can pile up and sometimes , not often, fix problems and speed up the computer a bit.

Here's a shot of a scan I just did. Not a lot, 84 I think. Just from Windows registry tracking everything you install or change, basically. Keeping settings for programs as well, that you may not have any more.

Anyway here's the shot, and I run it occasionally cause after a while there is 100's.

Remember that the registry is sorted and uses binary search when looking for keys. For those of you without computer science education, this means that to find one key out of 4.2 billion, only 32 compares are needed. In other words, even cleaning out thousands of entries is pretty darn irrelevant :)

(Oh, the binary search is per key (and subkey etc), by the way - where do you find more than a few thousand sub-key entires?)

I have a Vista x64 laptop. I've tried several cleaners and have come to the fact that such utilities could do much more harm to Windows rather than repair it.
I was adviced to try Digeus Registry Cleaner (http://www.digeus.com/products/regcleaner/index.html) and since then I've been using it for a couple of monthes.

Sorry to bump old thread. But i've found old Jv16 ergistry cleaner (last freeware version) searches for more absolute registry keys than CCcleaner's Registry cleaner. I don't get it why such huge difference in finding out registry keys.
Title: Re: What's the best registry cleaner? Ask Leo says: none
Post by: Innuendo on July 06, 2009, 12:06 PM
Since you asked, jv16 is more aggressive with its search results and marks those that it thinks are most likely safe for deleting.

CCleaner is more conservative in its results and only marks those that it knows for a fact are safe for deleting.

There is no real reason to clean your registry unless you are OCD about it or there is something in there that is seriously screwing up your system. Since the registry is in a database format doing thinks like cleaning, optimizing, shrinking, compressing or whatever fancy names these programs put on their functions will not gain you any speed-up at all when your OS accesses it.

Post by: cyberdiva on July 06, 2009, 01:26 PM
It's been MANY years since I used the free version of JVPowerTools, so I don't recall the specifics.  I do know that as far back as 2005, the paid version had two settings: Normal and Aggressive.  The number of items found was greatly increased if you used Aggressive.  I almost always used Normal.  The current version (JVPowerTools2009) has a four-point scale for you to select from. It goes from "Emphasize safety of the Registry Cleaner engine over both scan speed and the number of found errors" on one end to "Emphasize number of found errors and speed of the Registry Cleaner over safety and accuracy."  Of course, in all cases you are asked whether you want JV to make a backup of items before fixing them.  I always say yes, but fortunately I've never had to make use of the backup.

I can't comment on Innuendo's view that registry cleaners are usually unnecessary.  There do seem to be two camps about this.  All I know is that I'm forever installing and moving and renaming and uninstalling files/programs/whatever, and given how I use the computer, I tend to think that using a Registry Cleaner can be helpful.  But I don't know enough to be certain about this.

Trouble with loading up old images, is then I'd lose all the improvements I've installed on my system.  Likewise for me, virtual OS stuff seems more pain than it's worth.  Sandboxie I like.  When I'm done running the program in the prophylactic, I can just kill the sandbox and stop the Sandboxie service.  If only it ran in Vista64! :)

I run my system pretty lean anyway. I don't really feel the need to wipe my system partition. I do an image backup every few days to guard against disaster.  About the only thing I use to optimize the registry is NTREGOPT, and then only every few months.  Just seems to boot smoother for awhile after running it.

Well, I do occasionally use a sandbox, but one problem is that you don't get an idea of how a piece of software behaves during bootup.  I was testing one anti-malware program that worked fine...until I rebooted.    It then apparently got into a pissing contest with my anti-virus program, with the result that I couldn't even complete the boot process.   I've kept the anti-malware program on my system, but only to run scans, not to work in real time and not to start at startup.  But testing it in a sandbox wouldn't have revealed this very important problem.

Hi Folks,

Cyberdiva, one thing I noticed about SuperAntiSpyware (generally top-notch) was that .. even though I simply wanted it for an on-demand scan .. it was very pushy about putting stuff into the boot-time (possibly hoping that I would need it some day on a real-time upgrade .. clearly it could check for any updates at the beginning of an on-demand run).

Wondering .. was SAS involved in your unruly school children fight ?

As for registry cleaners, probably the best single thing to do is to uninstall with Revo Uninstaller rather than only Add/Remove.  After each uninstall you will end up deleting a couple of paths and/or registry entries that would have been left over.  The registry cleaning industry, when it is not outright sham and scareware, is much ado about very, very little.  If you happen to know a certain type of registry entry is quite recognizable and harmless, you could delete them with CCleaner or Eusing or somebody (the more conservative the better) .. however generally your time would be far better spent elsewhere.

btw, a good number of the techies on the net make $$ one way or another, directly or indirectly (google ads) with the sham & scare products, so they tend to not want to bite a feeding hand and say .. e.g. .. "beware of all the uniblue and paretologic and any google-advertised registry cleaner and speedup products, they are junk and dangerous".  

The situation with registry and drivers are similar .. when your system is running smooth and decent, a good way to bring that smooth running to a screeching halt is to do an auotmatic software-directed "cleaning" (registry) or a software-directed "update" (drivers).  And the registry is the more dangerous of the two.

Shalom,
Steven Avery

...Likewise for me, virtual OS stuff seems more pain than it's worth....

Seems to me you haven't looked deeply into it.  Once it is setup, it is by far the easiest way to go.  Setup isn't even all that difficult.  Personally, I suggest either VirtualBox (freeware from Sun/Oracle, at least for now) or VMWare Workstation (expensive, but comprehensive).  VMWare in particular makes development easy by fully supporting branching and snapshotting.  In other words, you set up the software, install a "gold image" and then take a snapshot.  From there, you can branch new versions of that image and it only saves the differences (conserving space), while still providing a fully functional PC appearance.  Go with a different program?  Just spin up another branch.  Want to delete everything?  Just delete the root image and wala, the rest is gone too.  VirtualBox supports some of this, and is working toward full support for branching of snapshots, but isn't quite there from the last version I have used.  That said, if you have the space, there are other ways around it.  Either way, it is very simple, though there is a little bit of a learning curve before it becomes easy.  If you had the time, I figure 4 good hours learning and working with it (after installation) should familiarize you with most of these types of functions and how to work around any limitations.  That, to me, is really simple for this powerful of software.  Maybe it is just me though...

Hi, Steven.  No, actually, it was another highly regarded program, Malwarebytes Anti-Malware Pro.

As for registry cleaners, probably the best single thing to do is to uninstall with Revo Uninstaller rather than only Add/Remove.  After each uninstall you will end up deleting a couple of paths and/or registry entries that would have been left over.

Yes, I've been using Revo, thanks to many enthusiastic recommendations here on DC.  I'm very pleased with it, but I do have two minor reservations.  One is that at times I can't tell whether the Registry keys Revo wants me to delete are the right ones.  I think my confidence was undermined a bit by one time where I really felt that it was giving me incorrect advice.  I no longer remember what that situation was.  But since then, I've been a little uneasy, though I usually do follow Revo's advice.

The other reservation has to do with its setting a restore point each time it uninstalls a program.  On the one hand, that makes sense, but on the other, I've set my computer to allot relatively little room to restore points, and there are times when I fear I could use up my self-imposed quota just by using Revo multiple times in a day or two.

The situation with registry and drivers are similar .. when your system is running smooth and decent, a good way to bring that smooth running to a screeching halt is to do an auotmatic software-directed "cleaning" (registry) or a software-directed "update" (drivers).  And the registry is the more dangerous of the two.
I'm sufficiently superstitious that I don't want to declare publicly that I've never had a problem with my registry clearner, but...  :)

Post by: MilesAhead on July 06, 2009, 08:18 PM
@steeladept I played around with VirtualBox.  Also the MS incarnation of the same strategy.  I think if I was going to do virtual I'd want something that just uses the Shadow Copy service and is nearly automatic. Unfortunately, like Sandboxie, I haven't found one for 64 bit that didn't appear to be dead(a la Disk Write Copy with a forum that hasn't had a post in 6 months or a program update in 8.)

Besides, I'm always installing small utilities, and tweaking my system.  So now I have to invest in some software that allows me to "save the changes" etc.  Why do all that when I can do a system image save in 15 minutes? If I was doing software testing for a living that's another story.  But for me the Sandboxie modus operandi seems most convenient.

Everyone has their own preferences. If it works for you more power to you. :)

-cyberdiva

All I can tell you is of my own personal experiences. I am a software junkie. If I have a software need (yes, need, dang it!) I will relentlessly search till I have found every program that will fulfill that need & I will end up installing a bunch of those till I finally have the one I consider to be best. I do this for every program I have on my PC. Sadly, it doesn't end there. Every few months I go check out all the new developments in programs and if they look like they can usurp my current choice I install them to give them a try out.

Everything I don't keep, of course, is uninstalled. Compound this phenomena with dabbling in PC games (I'll install games, try them out and after I've beat them or gotten bored with them they are uninstalled) my registry probably has a cubic butt-load of irrelevant obsolete entries.

I never do any registry maintenance and I don't have any program compatibility problems nor does my system run any slower than when I first installed my OS.

Actually, the only problems I have on my system from time to time are those evil little programs you install that covertly commandeer all your file associations behind your back. Fortunately, there aren't as many of those as there used to be and UAC blocks almost all of the remaining offenders.

Side note: Though I have never used it I have heard wonderful things about Total Uninstaller. If someone were looking for something that does what edbro talks about in his post then Total Uninstaller would be the first one I'd try.

welcome to the club.. probably a lot of us on DC like that.

HOWEVER.. i have come to believe that one should avoid whenever possible installing any program on your pc that you don't intend to keep installed for a long time.

INSTEAD.. test these programs in a virtual machine -- there are very good ones now: VmWare, VirtualPC, VirtualBox, etc.  These programs make it completely painless to evaluate programs without any risk or leftovers on your real pc.

Especially when trialing lots of alternative programs, since most of the programs you don't have to use for more than a few minutes to know it's not for you.

I think what we need is an automated gizmo to clone a mini-OS from the system partition, to a blank partition in like 10 minutes.  Then try your stuff out.  If it gets hosed, wipe and recreate it.  No messing with settings.  The program(which I have no intention of writing I must say) should do all that by analyzing what you've got on the "real" OS partition.

Reboot, install a bunch of junk, if it goes sour, reboot the "real" OS and rerun the mini-OS creation tool.

I was just directed to, then helped immensely by Revo a few days ago when I had a nasty little problem (http://www.gemx.com/forum/index.php?topic=168.msg424#msg424) with LetMeType. Revo Uninstaller was simple to use & very effective. But I will still take Carol & mouser's advice & install VirtualPC when I install Windows 7.

Cyberdiva, I has the same issue when asked if I wanted to delete certain registry keys.
So, I allowed it to delete the ones that obviously came from LetMeType & left the rest alone.
Haven't heard from that program since, so I'm fairly certain everything's OK.

The other quandry is when uninstalling if you get that "do you want to delete shared library x.dll? ... nothing is using it" query.. then you delete it and stuff is hosed mucho.

If you religiously monitor each installation with tools like Ashampoo Uninstaller or Total Uninstaller, you can easily wipe out everything that gets installed, including registry entries. I use Ashampoo and try to monitor each new installation.

Not a panacea in my experience - often applications build dependencies based upon the order in which things were installed (which is why sometime trying to uninstall an MS hotfix will wran you that it could break a specific list of applications that were installed after the Hotfix). The trouble with AU and TU is that they are blunt tools - they both remove everything that changed during the installation of the program irrespective of whether later applications rely on some of those components. In an ideal world the installation process and uninstallation process should keep track and avoid these problems but with the plethora of installer developers that are used this is very unlikely to happen in Windows. As far as I can see it would simply things enormously if the installation/unintsalltion/component registration and tracking were all standardised by MS so that proper monitoring of dependencies could be performed. The trouble is too many people would scream anti-trust these days but I would argue that managing installation and uninstallation of software should be a core function of an operating system - not the developer.

I think what we need is an automated gizmo to clone a mini-OS from the system partition, to a blank partition in like 10 minutes.

You can sort of do that - just use standard Partition Management software to clone a partition to spare disk space and then edit Boot.ini in XP or use BCDEdit in Vista/7 to create a new boot time entry which will make a bootable partition from it. Reboot your system and you can start up the second partition (your Windows may not be activated though - you'fd have to try it and see - I'd guess it might remain activated on the same drive but may not be on another physical drive, especially if it is a different manufacturer or drive type, eg PATA vs SATA).

An alternative is to use VMWare which can build a virtual machine based on a physical installation. You just tell it which partition to clone to build the VM. I'm not too sure what happens if you clone the currently running partiton though ;). I have to confess I haven't tried this and didn't really know about it until recently when I rebuilt a VM from VMWare version 4 to gain access to some features only available in 6.5 (multiple monitor support).

How about Universal restore in Acronis True Image ? You should be able to restore a VM to physical hardware using that. Just use TI (with UR) in the VM and write the image to DVD or a spare partition and then use the recovery media to restore it to a physical drive.

Glary has a decent startup manager and junk file cleaner.
It will do a backup for any function to undo changes.
Don't let it autostart, it will want to.

@registercleaner:

jv16 Powertools is a very good all-around file maintenance utility. I use the 2009 version; I believe that the 2006 version was the last free one - I used it back when it was free and have continued to use it since it went commercial. The developer spent a good number of years developing Powertools and providing a fair amount of support and I felt it was only fair to compensate him when he decided to make it his full-time job.

jv16 Powertools 2006 was mature by then and a very good utility. The only thing I don't know is up to what version of Windows it supports. I don't think I would even attempt to try it on Vista or Windows 7. jv16 Powertools is IMO one of the safest such tools available; its default settings have it make a full, restorable backup of your registry each time you run the registry cleaner. Also it does not automatically delete any registry keys unless you very specifically configure it to do so, and the settings dialog shows a strong warning NOT to set it that way. I cannot remember offhand whether or not Powertools creates a restore point each time; however I always create a restore point manually prior to performing any kind of registry cleaning or editing.

Now let me say that I don't believe that Windows needs to have the registry cleaned up on a regular basis, or even just because you think it might need one for the heck of it. I only use it when I install a program that for some reason turned out to be not compatible with my particular system and writes/changes a lot of registry settings. Many - most - programs do not remove or restore registry keys when they are uninstalled, and very occasionally that can cause some problems. If they are big problems I usually try to clean up after the program myself using the registry cleaner. If that doesn't help and there are no other widely suggested repairs, then I just reinstall the operating system. Of course I keep very extensive and frequent backups of all my data files and program settings.

Hope this helps!

Jim

I use JV16 quite a bit for much the same reason J-Mac described.  It also has some nice functions related to file and disk management.  I don't worry too much about trashing the registry because:

I've found it's very unlikely that JV16 will cause any damage if the "Fix" option is selected instead of the "Delete" option.

JV16 will optionally backup all changes it makes.

I use ERUNT to back up the registry every day, first thing in the morning.  Takes thirty seconds.

I create a backup image weekly using BootIt NG.  Takes twenty minutes.


No worries.

And the backup is on by default - you would have to go into settings and turn it off manually. And believe it or not I have seen forum posts by users who have done exactly that and then did an "Oops"! Hard to believe... What did they think they were saving?

I use ERUNT to back up the registry every day, first thing in the morning.  Takes thirty seconds.

I have always used ERUNT also - Department of Redundancy Department!! - but I haven't yet checked to see if it is compatible with Windows 7. Do you know, mrainey?

Per the developer:

"ERUNT and NTREGOPT in their current versions 1.1j are still compatible with Windows 7, but as in Vista, they will only work correctly if you turn off User Account Control in Windows' Control Panel (move the slider to the lowest position).

Also, a problem has been discovered which on many systems causes ERDNT and NTREGOPT to display a "RegSaveKey: 3" error when optimizing / restoring the BCD00000000 hive. The cause is that after a clean install of Windows 7, the BCD part of the registry which contains Windows' boot configuration data resides on a hidden system partition with no drive letter assigned in Explorer. You can simply ignore this error and continue, or as a workaround, open Disk Managemant in Control Panel and right-click on the partition displayed as "System Reserved" to assign a drive letter.

Future versions of ERUNT and NTREGOPT will of course have these issues fixed. Keep an eye on my homepage for updates."

Just wanted to add to the discussion regarding registry cleaners. If your someone who is technically proficient then you won't need to use them in most cases.
You will manually resolve any issues or just redo the machine. But nowadays you have a massive amount of users who have not idea about the technical side of
issues. You would definitely not want them messing around with the registry. Also for them to redo the machine could be something they could not do.
I think registry cleaners today can help resolve issues regarding errors & performance.
Most of them will back up the registry before they make any changes and include registry and disk defrag features and memory optimising
software as well.
its definitely something that can save a lot of time.

There is a massive amount of registry cleaner software that will destroy a computer.

There are very few that would actually remove what it should and leave the rest alone.
No more then 3 regcleaners I would even consider using, if at all.

I don't run them anymore, but I used to.
And would argue for some for their usefulness.
Cleaning the temp files would be, and is better anyway.

Just to add, I agree with cmpm. Technically savvy individuals may benefit from using a registry cleaner, but only if they have the time, patience, and knowledge to wade through all of the "fixes" that a registry cleaner recommends. For myself, the kind of problems that I want to solve that involve the regisry can be solved by editing the registry myself or by using an application like Nirsoft's ShellEx or ShellMenu View. Under Vista and Windows 7 (and problably XP, for that matter, but I no longer remember), I've yet to see a problem that I can trace to registry BEYOND shell menu entries getting left behind after uninstalling an application (and hence the Nirsoft software's utility to me). Beyond that, the registry "just works".

YMMV

Post by: Darwin on January 31, 2010, 10:59 AM
If you religiously monitor each installation with tools like Ashampoo Uninstaller or Total Uninstaller, you can easily wipe out everything that gets installed, including registry entries. I use Ashampoo and try to monitor each new installation.

Not a panacea in my experience - often applications build dependencies based upon the order in which things were installed (which is why sometime trying to uninstall an MS hotfix will wran you that it could break a specific list of applications that were installed after the Hotfix). The trouble with AU and TU is that they are blunt tools...

I'm about five months late responding to this, but what the heck: I actually use Ashampoo Uninstaller to monitor the installation of software which I'm not sure that I am going to keep. I uninstall applications using Windows built-in removal feature or by going to the program's folder and directly running its "uninstall.exe" file. Usually, this is all I need to do. If I have subsequent problems - recalcitrant shell menu entries, for example - I can then view the Ashampoo Uninstaller file. This will list all of the changes made to the registry, and serves to guide me to entries specific to that application. This makes it easy to identify keys associated with whatever problem I am trying to sovle, almost invariably either orphaned context/shell menu entries or file extension assignments, so that I don't have search through my entire registry. Beyond this, I tend to ignore orphaned registry entries. I don't much care if there are keys left behind if they don't impair the operation of Windows or other software that is still on the computer.

I totally agree with Carol, though: I no longer use Ashampoo Uninstaller to uninstall anything, for all of the reasons Carol detailed. I did want to point out the utility of being able to track changes that a software installation makes to your system, though. Ashampoo Uinstaller allows me to target specific changes and make corrections. I don't, however, advocate using it as intended, which can lead to serious problems. Of course, there are free alternatives out there, I *think*, that provide similar functionality.

EDITED for clarity... (success?!).

Of course! But you can also install software on your computer without polluting your registry. This is an English language thing, I think. There is a saying in English that if you want to avoid the negative consequences of some action you should simply avoid that action altogether. For example, if you don't want to die in a plane crash, don't fly! To make some other examples: if you want to avoid slipping and hurting yourself in the shower, don't shower! Don't want to choke on a chicken bone? Don't eat chicken. Scared about a paper cut? Avoid paper.

I suppose, really, I read your comment in haste and interpreted it in light of the English saying described above. So I read it like this: ANYTHING we do on a Windows computer is going to affect, and potentially pollute, the registry. Therefore, if you want to avoid polluting your registry you shouldn't install any software on your computer. Now I realize that you probably meant it in the way that I rephrased it: just be careful about what you install on your system.

Langa is telling what most of us already know, but without the exaggerations...

Test-driving ‘free scan’ tune-up suites

By Fred Langa on August 8, 2012 in Top Story   

(...)  Just as with the previously-discussed tools, when I drilled down to examine these problems, some (such as junk files) were real, with most of the rest either exaggerated or simply wrong. (...) WinZip System Utilities Suite (and the other scanners discussed below) seems to deliberately inflate the seriousness of some items — for example, calling its own website’s harmless cookies “privacy traces.” (...)

(...) ... the software I test-drove for this article clearly seems aimed at inexperienced users who are more likely to purchase “repairs” when confronted with frightening reports of critical and numerous system problems.

Those, however, are relatively minor transgressions compared to reporting serious problems where none exist, such as flagging fully up-to-date drivers as “ancient.”

All of this seems designed to make your PC appear to be in dire need of paid-for repairs, when in fact there appear to be no real operational problems.

The only problem though is that something - and I suspect CCleaner, but cannot prove it (i.e, it's not repeatable) - sometimes seem to zap some of my bookmarks in xplorer².
Since the xplorer² bookmarks and other settings are held in the registry, my workaround is to periodically export a copy of the xplorer² settings, to a .reg file, so that I can reset/reinstall them after they get zapped.

I have long been a faithful student of Koroush Ghazi's TweakGuides Tweaking Companion 01 v3.0 - Windows XP (2006-01).pdf (http://docs.google.com/open?id=0B9rIby-RfgLNYzZZUjJwNGNWUUk) and later TweakGuides Tweaking Companion 02 v1.2 - Windows 7 (2011-02).pdf (http://docs.google.com/open?id=0B9rIby-RfgLNdnMxNzlnTG5aTmc) (click on links to view/download).

In both, he suggests the registry-cleaning and tweaking software to use, but it does seem that there was potentially more to be gained from deliberate maintenance/cleaning of the XP registry than of the Win 7 registry. He doesn't say to not use maintenance/cleaning tools in Win 7, but suggests which to use - which fitted with my theoretical approach that the registry is just a database and so could benefit from its obsolete records being periodically weeded-out and the database size being optimised/compressed. Makes it more efficient.
It's really just part of what I was taught as being good "system housekeeping" practice. Sure, it's a nuisance and it's unproductive maintenance, but that's the point - it is maintenance, as is maintaining efficient Group Policy through tweaks using the group policy editor.

Why do you use it, though? Except for a few specialized situations, doing "registry cleanups" is almost entirely superfluous on NT based Windows versions. The space savings are negligible, and because of the data structures and algorithms involved in the registry, you're unlikely to see any speed gains.

You'll want to make sure the hive files aren't too fragmented, but that's about it.

Because it's a decent piece of software that's decently priced. If you only need basic archive operation, you should probably go for 7-zip (it's file manager misses a few convenience things here and there which would annoy me in the long run, but it's good enough that I don't have WinRAR on my work laptop) - but WinRAR does have a bunch of additional features (NTFS streams and ACLs and pretty darn comprehensive command line features).

That said, WinZip is still pretty good, it is only a bit too pricey.

Things like date/time specifiers in the output filename, and "clear Archive attribute" combined with "only add files with Archive attribute set". (Those are features I've used a fair amount - but it supports a lot more stuff from the command line, including features that can be useful for scripting).

Also, format wise, RARs Recovery Records have saved my ass, and native multi-volume support (rather than 7z's split/reassemble) is nice when dealing with unreliable protocols like FTP or HTTP.

No, I didn't miss the ".zipx" format, it's those "not universally supported extensions". On a lot of platforms, zip support means info-zip zip/unzip, which doesn't handle those. And while RAR isn't open source, it does at least have source code for the decompression, with a liberal-enough license that it's a usable format. (Is there any source around for the zipx extensions yet, or just the half-assed "technote"?)

Using CCleaner:
I use CCleaner:
(a) for the simple reason that it theoretically allows for good practice in system housekeeping, and my training is to take this practice approach (belts and braces).
(b) because experience has led me to trust that Koroush Ghazi is probably qualified regarding what he discusses in his technical handbooks.

It's really all about risk avoidance. For this reason, I would recommend using CCleaner or another reputable registry cleaner.
I don't have an opinion on whether CCleaner (or any other registry cleaner) is good or necessary though, as I am not qualified to judge, not having researched the field.

IainB, it seems a lot of people are still stuck in the Win9x era regarding some things. "I've always done this, it mattered back then, so I'm just going to continue mindlessly doing it without researching if it's any use" kinda of mindset. I'm not familiar with Koroush Gazi (nor tweakguides), so he might very well have reasonable things to say - but recommending to run registry cleaners would not be one of them.

It's really all about risk avoidance. For this reason, I would recommend using CCleaner or another reputable registry cleaner.
You're more likely to run into trouble if you use a registry cleaner than if you don't. CCleaner might opt on the safe side, but still you're hardly going to prevent problems by running a registry cleaner (CCleaner can do other stuff as well, which might be more useful).

It might not be a very large risk, when you use a cleaner that isn't overly aggressive - in that case, it's just a case of not really gaining anything, plus the (slightly theoretical) argument that it's more risk doing changes than not doing them.

As for why registry cleaning doesn't gain you much (apart from some situations where software has actually broken stuff), there's two points:
1) you won't gain a lot of disk space. On my work laptop, my current user hive is 7 megabytes... that's a drop in the ocean on today's harddrives. Besides, if you compact the hive, adding new nodes will cause file fragmentation, whereas while not shrinking internal slack space can possibly be re-used.
2) node lookups are pretty darn efficient. Iirc, it uses a binary tree structure, so node lookups are fast, even if there's a huge amount of them. (OK, you can gain some speed on during full-registry searches, but that's not a very typical usecase :)).

Registry cleaners remove things that are (perceived as not being necessary) not being used. The problem is many of these items are imperative for things that one frequently needs later. I'd say that easily 80% of the times I've worked a call where a .NET based business application install/update went down in flames were directly caused by someone there deciding to "Tidy-up" a bit with a registry cleaner.

Registry cleaning is best compared to garage cleaning ... Sure the place sparkles when you're done, but... You typically end up needing something you threw out about a month later.

The Top Story: "Are system/Registry cleaners worthwhile?" (spoiler: surprisingly one of them is!)


Are system/Registry cleaners worthwhile?
By Fred Langa on July 15, 2015 in Top Story   

As Windows and third-party software have evolved over the years, Windows Secrets has periodically put various Registry- and system-cleanup products through their paces to examine the claims made by and about them.

For example, most cleanup software claims to streamline and shrink the Registry by removing obsolete, erroneous data and broken links stored there. Other products claim to do more, such as removing junk files, reducing boot times, and improving overall system performance.

Back in the days of Windows XP, third-party system cleaners were of real value in removing detritus from the operating system. But the current versions of Windows have many more built-in tuning and self-repair options. So do third-party cleaners still deliver any real-world benefit? Do they live up to their impressive claims?

conclusions
If you follow the recommendations in ##those articles##, then your PC will most likely also be lean, clean, and running well — without the assistance of any third-party cleaning tool.

A second related takeaway from these tests: If your PC is at all healthy, it’s unlikely you’ll see miraculous results from any commercial cleaning tool — and certainly no “47 percent faster boot times.”

My third and final takeaway: I’ll continue using — and recommending — lightweight tools such as CCleaner for routine cleanups. As mentioned earlier, this test (one cycle of software setup and knockdown on already-clean systems) didn’t leave a lot to clean up. But each cycle of software installs, upgrades, and uninstalls leaves behind some digital debris. Over time, it adds up and can become a significant source of slowdowns and clutter.

These tests tend to confirm that the manual cleaning methods mentioned above, plus lightweight cleaning from third-party tools such as CCleaner, might be all you need to keep a PC operating at or near best-available levels of performance.

I also worry about over-cleaning. I have to wonder about the high fault numbers reported by jv16 PowerTools X and Advanced SystemCare and what the two products are actually cleaning. (In some cases, the cure might be worse than the disease.)(...)[ You are not allowed to view attachments ]


It's summer, so the article is a cook-up from their articles last August.
