Turn off User Account Control (UAC)

[tech2game]

The most annoying feature of Vista, UAC interrupts with a pop-up dialogue box, consistently asking if it's OK to run things. It serves two purposes, both to protect the user in case a malicious program is run, and to get programmers to write more secure code. Which is all very nice, but it completely gets in the way of day-to-day work. Here's how to turn off the annoying nuisance forever.

Click the Windows button in the bottom left-hand corner.
Click Control Panel.
This step will change depending on whether you're using the Classic view for Control Panel or not.
If you're using Classic View, double click User Accounts
If you're using the default view, click on the green User Accounts and Family Safety link, then the green User Accounts link
There should be a link here, Turn User Account Control on or off. Click it
Click Continue in UAC for the last time
Uncheck User Account Control (UAC) to help protect your computer, then click OK
A notification will pop up — save any documents you have open, and choose Restart Now to reset your computer
Never deal with UAC again!
