Warning! Do NOT apply XP SP 3!

Easiest way to deal with something like this is to install Windows on a separate harddrive and keep your paging somewhere other than where Windows installs. You know...install Windows on a small partition that you put nothing else on. Ever. That way, when something breaks (even Linux isn't perfect, kids) you can just reinstall it without too much worry. Yes, it's a bit of a pain but, for the best computer results, you should format and reinstall like once a year anyway.
