If you plan to switch off UAC make sure you've got some really good anti-virus software installed & scan everything executable before you use it. I know most people do that anyway but it's worth repeating as I forgot the other day & had to spend a couple of hours yesterday reinstalling Windows to get rid of a virus.

Oh yeah check out www.blackviper.com/ to get a smoother running Windows, just remember to play "safe". ;)
