How to Completely Disable ‘User Account Control’ (UAC) System-Wide in Windows 11

User Account Control (UAC) is a fundamental security feature in Windows 11 designed to prevent malicious software from silently making unauthorized changes to your system. When an application attempts to modify system files, install new software, or change registry keys, UAC temporarily dims the screen and demands explicit administrative approval before allowing the action to proceed. While this provides an essential layer of security for average users, IT professionals running automated deployment scripts or power users managing heavily customized offline environments often find the constant UAC prompts highly disruptive to their workflow.

This guide explains how to completely disable User Account Control system-wide in Windows 11, granting all administrative applications silent, unrestricted execution rights.

Disable UAC via the Control Panel

The most accessible way to disable UAC is through the legacy Control Panel interface, which allows you to adjust the sensitivity of the security prompts.

1. Click the Start Button (or press the Windows key) and type UAC into the search bar.
2. Select Change User Account Control settings from the search results.
3. The User Account Control Settings dialogue box will appear, featuring a vertical slider on the left-hand side.
4. Click and drag the slider to the very bottom position, labelled Never notify.
5. Click OK.
6. You will receive one final UAC prompt asking you to confirm this change. Click Yes.
7. Restart your computer for the system-wide policy to take full effect.

Once set to “Never notify,” applications running with administrative privileges will no longer trigger screen dimming or confirmation dialogue boxes. They will simply execute their tasks immediately.

Disable UAC via the Registry Editor (Advanced)

For system administrators building unattended deployment images, you can completely disable the UAC engine at the registry level.

1. Press Windows Key + R to open the Run dialogue box.
2. Type regedit and press Enter to launch the Registry Editor.
3. Navigate to the following path:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
4. In the right-hand pane, locate the DWORD value named EnableLUA.
5. Double-click EnableLUA and change its Value Data from 1 to 0.
6. Click OK and close the Registry Editor.
7. A system reboot is absolutely required to finalize this registry modification.

Warning: Completely disabling EnableLUA fundamentally breaks several built-in Windows 11 security mechanisms, including Universal Windows Platform (UWP) sandboxing. Do not perform this action on a machine connected to the public internet.
