Regarding the reluctance to do a System Restore: I see this occasionally and think it's just due to a misunderstanding what System Restore DOES and DOESN'T do:
First, it's a very easy process to do: The following gets you there:
All Programs> Accessories> System Tools> System Restore
Once there CHECK 'restore my computer to an earlier time'> Next> choose any date in
BOLD on the left screen> Next.
That's it- all there is to it. Let the restore take place. System will reboot when through.
The system creates restore points about once every 24 hours, if the computer is on.
YOU can create a restore point when ever you want:
Follow the path to the restore screen: click on 'create a restore point'> Next> close when through.
TIP: make a shortcut for System Restore and drag it into the Quick Launch Toolbar.
The is NOT the bigggggggggg restore when you go back to Last Known Good Configuration.
This is a helpful way to undo some small thing that may have caused a problem, like an update.

Windows XP> what it excludes:
excludes any file types used for users' personal data files, such as documents, digital photographs, media files, e-mail, etc. Also excludes the monitored set of file types (.DLL, .EXE etc.) from folders such as My Documents in Windows XP
Vista:
Windows Vista, this set of files is defined by monitored extensions outside of the Windows folder, and everything under the Windows folder.
What it monitors, when and how restore points are created, in a nutshell:
Up to Windows XP, files are backed up only from certain directories. On Windows Vista, this set of files is defined by monitored extensions outside of the Windows folder, and everything under the Windows folder.
So why? What do you think you'll lose?
I do not want to system restore.
