Vista - User Account Control (UAC) - Blacking Out of Screen

Information

This is when the screen goes dark when the User Account Control window comes up. This is called the Secure Desktop mode. It is enabled by default in Vista. This will show you how to enable or disable Secure Desktop for UAC only.

NOTE

This is the same security mode used when you log on or press CTL+ALT+DELETE.

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

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.
