A little update on the problem.
Well I fixed it, turns out it wasn't the UAC and it was me just being stupid. I have an ATi video card and I run ATT (ATi Tray Tools) and there is an option is General Options called "Agressive 3D Detection." This option in Windows 7 doesn't work correctly and requires it to be ran as admin.
So if anyone else has the problem I had, just untick that option and you'll be good to go.
