This article is pretty short, but I’ll try not to quote the whole thing verbatim, so you actually have a reason to check out the link I’m posting. =)

Open up Control Panel, and type in “UAC” into the search box. You’ll see a link for “Turn User Account Control (UAC) on or off”:

On the next screen you should uncheck the box for “Use User Account Control (UAC)”, and then click on the OK button.

…Well, damn, that was pretty much the whole thing. Go check it out anyway. =)
