For some reason I always manage to cause problems in my windows xp installation. Last night i noticed msconfig couldn't be run and the Help and Support service wasn't running and not in the services list. I suspect an third party installation utility to have removed too mayn things.
Short story: with all the different software out & the underlying OS not protecting itself properly, how can I use all my software and software installs conveniently without problems appearing.
Long story:So as a precaution I ran the system file checker (sfc /scannow). Afterwards, I recommend never to do this! It replaced a series of files - After a reboot I got a blue stop error. Booting into last known good mode turned out to boot into the middle of a daemon tools install and therefore broke a system level device driver Daemon Tools installs (sptd.sys).
I couldn't boot into normal mode, and as system restore was off (can't remember doing that) I couldn't fix it. Now see short story.

Options I've thought of:
- Buy a big additional /external harddisk + Acronis Trueimage and make weekly images.
Problem with this is that when I find out that there's problems it will be a pain to revert to an identical installation without problems. - Bare XP install + Using a virtual PC to use most of my software with.
It's an inconvenience, and it wn't work for games + movies due to no video accelleration (and more). Booting up two oses is a defeatist attitude. - Bare XP + Altitis AVS virtualising all apps.
Still makes installs inconvenient, but should theoretically keep XP clean, and enable software packages on demand. Unknown how this works with software updates such as Adobe's updater, and startup items.. Also I don't know if this works with games? (does it affect performance). No experience. - Don't install as much software.
I'm too curious - and what use is an OS that you shouldn't use software with? - Move to different OS(x)/Linux --
Either too expensive at this time or will cause just as much time fiddling to get thigs set up + vmware to run certain programs. 
- Some magic idea you know of that I have not come across.
Please tell.
So sorry for this long post but this issue has been annoying me since 2001. Any tips on living with Windows XP + a lot of software would be appreciated!
