If you are getting weary of Windows Vista User Access Control (UAC) popping up confirmation dialogs but (like me) are reluctant to turn it off since a lot of what it does is actually good, this might be just the ticket. I found this via Brad Linder at DownloadSquad this morning and plan to keep in around for software install sessions and other occasions when I know I'm going to get "beeped" frequently as a result of actions I know I want to take.
TweakUAC is a nifty little freeware application that lets you quickly turn UAC on or off (which requires a reboot), or sets UAC to operate in quiet mode. What's quiet mode? It means that UAC is still running, but it won't display warnings if you're logged in as the administrator. Best of all, no reboot's required, so you can switch to quite mode while you're tweaking your software setup, and switch back to normal mode when you're done.
TweakUAC is an executable, meaning there's nothing to install. But if UAC is running normally on your PC, you will have to deal with a UAC prompt every time you run the program.
