This is an easy method that you can use to disable the annoying User Account Control (UAC) from the control panel GUI interface in either Windows 7 or Vista.

See enable or disable UAC from the command line to do it from the trusty command line.

Note: Disabling UAC will lead to a less secure system, so be warned.

Disable UAC on Windows Vista
Open Control Panel, and type “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.

Unfortunately you will have to reboot your computer before the changes take effect, but you will be all done with annoying prompts.

Disable UAC on Windows 7
Windows 7 makes it much easier to deal with UAC settings, and in fact you don’t have to completely disable UAC if you don’t want to. Just type UAC into Start/Run, Start/Search or Control Panel search boxes.

You can simply drag the slider up or down, depending on how often you want to be alerted.

If you drag it all the way down to the bottom, you’ll have disabled it entirely.
