Hello, I literally just finished installing a clean, legit version of Windows Vista Home Premium. I am trying to turn off user acct control, and for some reason - this company and only this one seems to hault when i click it. It doesn't freeze.. it just doesn't do anything like a broken link. It shows it loading for maybe 1/5th of a second then does nothing. What is wrong with this? Thanks!! I am using NVIDIA 8800 GTS pcie card + amd 2.8 ghz dual core processor + 2 gig ram.
