alot of people bash Windows/MS.. I run Win 2kPro and have NO PROBLEMS, no blue screens etc. My 6yr old son uses Win 2k Pro for games and even his system runs PERFECT. I use my system every day and leave it on 24/7..it runs without reboot for at a minimum of 2-3 months unless I install something that requires a reboot.
So if you're having a problem with windows, maybe its your hardware or a user error.
