Here are my system specs:
Windows Vista Home Premium
AMD 64 Live! X2 Dual Core 4400+
Nvidia 8500GT 512MB 16x PCI-----------Driver 169.25 WHQL
Realtek HD Audio Integraded through the Nforce 430-----------Driver R1.85
2GB Corsair DDR2 RAM
350GB Hard Drive with 207GB free.
I currently use Norman Anti-Virus, which has the latest update as of today 01-27-2008
I think that if I paid for the premium version just to have those options and I can not use them, then I wasted my money and should have stuck with XP Pro SP2...good thing I am dual booting with my XP install so I can still use it due to incompatibility issues with Vista and some of the games I play.
