It still gets really messy though. Yes, it is better than Windows 98, but it still has a long way to go to get to where you don't really need to defrag it.Integra Type RXP makes much better use of how it allocates and repositions things when you install/uninstall programs.
I'm not saying it's completely uselss, but its far less effective on XP than it is on 98.
Event1. Reinstall Windows
2. ??????????
