Er, Windows XP is the meshing of 9x and the NT core (2000), the resulting mess being something with the stability of the NT kernel but the feature bloat of ME which can cause the OS to seem unstable. (How's that for a mouthful?

) Disable something like System Restore and you remove a lot of fragmenting of your hard drive.
If you disable the extra BS, XP looks a bit like Windows Server 2003 without the server. And please, no one ever mention the horrific travesty that was Windows ME. It induces nightmares beyond human imagination.
Posty: Windows 2000 is the first NT OS to not be a nightmare to manage and being built on NT, it has something the 9x core seems to lack: stability. Go ahead, try to bring it down with normal use. I'm sorry, but it's not a lesser OS. The lesser OS is 98 and under. I refuse to install XP because of the bloat; I'll take Server 2003 any day over it.
(Excuse the fire, but I hate when someone bags on an OS without knowledge of what they're talking about. In the ~7 months I've had this computer, 2000 has only managed to bluescreen once: during a game that has a known bug on my video card.)
