[How To] Prevent UAC from Dimming the Background

UAC is a bit annoying, but it’s worth it. If you’ve got an old computer that’s already struggling to run your programs – UAC can give you a hard time. First, the screen dims off and then everything stops for a while after which you see the UAC prompt. The entire process repeats again before you can get back to your work. In this guide, you’ll learn how to prevent your screens from Dimming thus making UAC a mere pop-up.

  • Click Start and then type REGEDIT in the start search.
  • Now, navigate to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

Regedit

Regedit Change

  • You’ll find the entry ‘PromptOnSecureDesktop’ on the right side. Click on it and set the value to 0 instead of the default 1.

You will now see just the notification every time UAC pops-up. No more screen dimming!

UPDATE: Thanks to Ashutosh Mishra for pointing out that this can be done easily by just getting into UAC’s Settings [inside Action Center].
