How to Enable or Disable User Account Control (UAC) Blacking Out of Screen in Windows


information   Information
This is when the screen goes dark when the User Account Control prompt displays. This is called Secure Desktop mode. It is enabled by default in Windows.

This tutorial will show you how to enable or disable Secure Desktop mode when the screen dims for a UAC prompt in Vista, Windows 7, and Windows 8.

You must be logged in as an administrator to be to do this tutorial.

Note   Note
This is the same security mode used when you log on or press CTL+ALT+DELETE.
Tip   Tip
Disabling the UAC Secure Desktop will allow you to take screenshots of the UAC prompts, and will not freeze the whole computer screen while it waits for you to answer the UAC prompt.
warning   Warning
If you disable the Secure Desktop, you will be making your computer less secure. Displaying User Account Control elevation prompts on the Secure Desktop helps protect the user from unknowingly allowing a program to run with elevated privileges without their consent. Without this protection, it is much easier to create malware that tricks the user into approving an elevation request prompt that they really wanted to deny. The Secure Desktop helps protect against this because other software running on the machine is blocked from interacting with the user's interface. It is your computer and your choice.
