I'm running Windows Vista HP 32-bit on my laptop right now (used to have Windows 7 Ultimate RC 32-bit). The thing is, I miss the fact that in Windows 7, UAC could be adjusted so that the whole screen doesn't dim when UAC activates.

Is there software or a tweak that I could use to stop the whole screen from dimming when UAC goes on?

Update (thanks grawity): From MS, What are UAC settings? Because the UAC dialog box isn't on the secure desktop with this setting, other programs might be able to interfere with the visual appearance of the dialog box. This is a small security risk if you already have a malicious program running on your computer.

Windows Vista Business/Ultimate Users

To get to the configuration screen for this, type in security to the start menu search box. You should see the Local Security Policy as the top search item.

In the Local Security Policy window, browse down to Local Policies \ Security Options

Over in the right hand part of the window, scroll down near the bottom and find the item titled “User Account Control: Switch to the secure desktop when prompting for elevation”. Double-click on it to open it up, then change it to disabled.

At this point Secure Desktop should be disabled.

Windows Vista Home Users

You will need to open up regedit via the start menu search box. Browse down to this registry key:


Right-click in the right-hand pane and create a new 32-bit DWORD value called PromptOnSecureDesktop, setting the value to 0.

Downloadable Registry Tweak

Just download, extract, and double-click on the DisableSecureDesktop.reg file to enter the information into the registry. There’s also an included EnableSecureDesktop.reg file to put things back to the way they were.

Remember that you don't just disable "dimming" this way - you disable the entire "Secure desktop" functionality in UAC. It's called "Secure desktop" not without a reason. – grawity Feb 18 '10 at 19:30
