Well, Windows should be reinstalled every 6 months anyway... Yes, I know, XP has made it much better, but I still get pretty bad bit rot over time...

My thoughts exactly. I'm at the point where I can get 90% of it done in about 3 hours. I have all my apps installed on a separate drive, and all my important files, etc. get backed up before the install. So I basically format the C: drive during installation, and do my major software installs en masse. Then the utils and apps I don't use that often will get installed the next time I need 'em. In the mean time, my PC sure is a lot faster.
