Not supporting a 6 year old OS? What's next . . . requiring 3D hardware? It's a travesty I say.
C'mon guys - a copy of XP is like $90 if you know where to look. Prolly even less if you look hard. And it's way more stable.
I just wish MS would come out with a gaming OS that would turn off all the shite you don't need in order to eek out maximum performance without having to be an OS tweaking/config guru. Or at least the ability to reboot into a "gaming mode" or something like that.
