How to Prevent UAC (User Account Control) Blacking Out Windows Background

One of the most frustrating feature of Windows Vista is User Account Control (UAC) where user gets unwanted security  prompt while running any important application. It asks user to either allow the application or block it. When the UAC appears, the rest of the desktop fades out and you won’t be able to do any other task without selecting options given in UAC window.

If this feature annoys you a lot then you can tweak the Windows registry to make changes in UAC. After changing a Dword value, your screen won’t fade out with UAC. Here’s how you can do this:

1) Click on Windows Start button given on a bottom left. Now type regedit in the search field. Right click on regedit.exe and select Run as administrator.

2) When the registry editor windows opens, from the left hand side of the window navigate to:

HKEY_LOCAL_MACHINE –> SOFTWARE –> Microsoft –> Windows –> CurrentVersion –> Policies –> System.

3) On the right pane, you’ll see many options. Check out the option PromptOnSecureDesktop.

4) Double click on PromptOnSecureDesktop. Now set the Value Data from 1 to 0. Now press OK.

5) Close the Registry editor.

This change in registry will take effect immediately without the need of reboot.

Note: This method is only applied for Windows Vista Business/Ultimate Users. If you are Windows Vista Home user then you have to crate a registry entry. All you need to do is go to the path in registry described above (HKEY_LOCAL_MACHINE –> SOFTWARE –> Microsoft –> Windows –> CurrentVersion –> Policies –> System). Now on the right pane, right click and create a new 32-bit DWORD value.

Name the value PromptOnSecureDesktop and set its value to 0. That’s it. You won’t get dark screen when UAC prompts.
