Whenever you try to install a new program, run the Command Prompt as an administrator, or modify a system file in Windows 11, your entire screen suddenly dims. A stark dialog box appears asking, “Do you want to allow this app to make changes to your device?” You cannot click anything else on your screen until you explicitly click “Yes” or “No.”
This is User Account Control (UAC). It is a vital security feature designed to prevent malware from silently installing itself in the background. However, if you are a power user performing a massive system overhaul, or a software developer constantly compiling code, the constant barrage of UAC prompts becomes incredibly frustrating. You can completely block this prompt by dropping the security slider to its lowest setting.
How to Completely Block the ‘Allow This App’ Prompt
You must lower the User Account Control slider in the legacy Control Panel.
- Click the Start button, type UAC, and press Enter. (The search result will say “Change User Account Control settings”).
- A legacy Windows dialog box will appear featuring a vertical slider on the left side.
- By default, the slider is positioned at the second notch from the top (“Notify me only when apps try to make changes to my computer”).
- Click and drag the blue slider block all the way down to the very bottom notch, labeled Never notify.
- Click the OK button at the bottom of the window.
- Ironically, Windows will throw one final UAC prompt asking if you want to allow this change. Click Yes.
The change is applied instantly. From this point forward, when you launch an installer or run a program as an administrator, it will open immediately. Your screen will never dim, and you will never be interrupted by the UAC confirmation box again. (Warning: Because you have disabled this security feature, you must be absolutely certain that any files you download from the internet are safe, as they can now execute with full system privileges immediately).
