Windows Vista UAC (User Account Control) is a special feature specifically built to enhance better security for Vista system. When we are about to install a program or usually when we initiate an installer (exe etc), screen will goes dark as the UAC popup appears. It’s a very useful feature especially for newbies who can’t differentiate between safe installer or malicious one that might pose threats to the computer system. Apparently, advanced users find this feature is not really necessary for them.
As for Windows 7, Microsoft has already employed UAC control panel which works exactly the same as the small application in [method 2]. So you don’t actually need application in method 2. In fact, Windows 7 users don’t really need to delve into [method 1] to disable it. That said, it brings no harm for you to use either methods on Windows 7 UAC.
There are 2 ways to turn off the annoying Vista UAC.
1. First you need to type in “security” in the start menu search box and hit enter.
2. Local Security Policy window will appear. Browse into “Local Policies” by using left pane and double click on “Security Options”.
3. Locate the “User Account Control: Switch to the secure desktop when prompting for elevation” entry on the right pane.
4. Double click the entry and set it to “Disabled”.
5. That’s it and no more screen “blackout”.

No installation required and you just need to run it regardless of whenever it resides in your computer. Hate it, then simply hit the delete button, no need to unistall it.
