Microsoft introduced the User Account Control (UAC) in Windows Vista and Windows Server 2008 to block activities requiring administrative privileges on Windows systems until an administrator permits them.
The company relaxed the feature in Windows 7 and Server 2008 R2 to make it less annoying for users.
A simple example of UAC kicking in on Windows 10 is the launching of the system's Registry Editor. Windows displays an UAC prompt whenever you open the editor on the system.
This prompt is fullscreen by default blocking everything else that is happening on the screen until the user responds to the prompt by allowing or preventing the action.
These prompts may or may not be annoying depending on how often they spawn on the system. If you work regularly with system applications or install new desktop programs regularly on Windows systems, you may want to relax the User Account Control settings to make UAC as a whole less intrusive.
The method described below will disable the "dimming" of the screen until the User Account Control prompt is answered but won't modify the feature in any other way.
This means basically that the prompt is displayed just like any other window on the screen and not exclusively on it.
The controls to do so are identical to those of previous versions of the Windows operating system. The guide may be useful to new users and users who forgot about them.
The changes take effect immediately. If you want to test them, try running the Registry Editor on the system. You should get a regular UAC prompt instead of an exclusive prompt now.
You may modify the User Account Control behavior further by modifying local security policies or Registry preferences.
The settings are:
Detailed information about each policy are posted on Microsoft's Technet website.
