Windows has a bunch of features that you don’t really need, especially if you are a more advanced user. One of these is the dimmed secure desktop, which (as the name suggests) dims the desktop when changes are about to be made to your system

If you're not a fan of this feature, you can turn this off. Here we cover when it makes sense to disable the dimming of the desktop with ways you can achieve this.

When Is It Advisable to Disable the Dimmed Secure Desktop?

The User Account Control (UAC) settings govern if and when the system prompts you to take a second look at when changes are going to be made to your computer. The Windows default setting is to dim the desktop to notify you only when apps (not you yourself) attempt to make changes to the system. This serves as a heads-up to impending changes to the system.

Having the dimmed secure desktop function disabled is pretty much the same as the default setting, barring a dimming of your screen. We have an article with a lot more on user account control and administrator rights if you’re interested.

It might be best to disable the dimming of your desktop if you use the default setting anyway and either don’t like to be confronted by a dimmed screen when you are making changes to your system or if it takes a long time to dim your desktop.

  5. Set it to Enabled to undo this setting.

Enable or Disable the Dimmed Secure Desktop via the Registry Editor

The third way to achieve this is to edit the Windows registry, which comes with its own set of cautions. When editing the registry, make sure you don't change anything you're not supposed to, else you may do damage to your system.

Here’s how to enable or disable the dimmed UAC prompt using the registry editor.

  1. Press the Windows key + R to pull up the Run dialog.
  2. Type “regedit” into the text field and hit Enter.
