If you want to avoid recording extraneous effects you need to run it with as few extra apps, processes and services running as possible.
TU wont remove the trial key in the registry, i tested a shareware program a while ago but didnt like it, so i uninstalled it with TU and when i tried it again recently, the program is expired.
TU doesnt remove everything.
Actually there's a "perfect solution to the above problems".http://www.symantec....ery/ngb40/index.html
It's the only Symantec software I use. I started with it when it was with Roxio.
It's like a time machine that rolls back everything (and I mean 100% of changes) on your computer to a previous time. How far you can roll back depends on how much space you allocate to it. So if you are paranoid about the changes made trialing software on your PC, then Goback is the software you are looking for.
For me, it has enabled me to roll back many kinds of problems, such as the famous BSODs, unruly trial software, or even a poorly tested Windows Critical Update ( https://www.donation...52.msg22841#msg22841
), and would have save grief for some whose system was trashed by a poorly tested virus signature update, recover data files that I accidentally overwritten (saved my life a couple of times) etc.
There have been a couple of times I had some problems with Goback over the years but they were few and far between.
Of course some have said that running it in the background consumes resources. In practice, I hardly notice any load and I have been using it for several years now even back in the days of slower processors.
I think IBM laptops have a similar roll back capability.
I have trialled TU once but never could convince myself that it could roll back software installations completely and only related to that particular software, since there are so many other processes in Windows that are running at the same time.
I might as well trial a software and if I think it's a no go, or windows update for that matter, I just Goback as if I never seen it in the first place. This, to me is the perfect software for the shareware junkie since we don't know what spaghetti changes they are making.
That way, I can keep my system stable for a long time.
