What Is UAC in Windows 10 and Windows 11, and Should You Disable It?

That User Account Control pop-up always seems to appear when you’re trying to get something done. You’re installing an app, changing a setting, or fixing a driver, and Windows suddenly wants permission to continue.

UAC protects your PC from unauthorized system changes, but repeated prompts can get annoying. This guide explains what those alerts mean, how to adjust them in Windows 10 and Windows 11, and how to disable UAC when a stubborn compatibility problem leaves you looking for a last-resort fix.

What Is UAC in Windows?

User Account Control, usually shortened to UAC, is a Windows security feature that asks for approval before an app makes administrator-level changes.

Think of it as a locked door between everyday apps and the sensitive parts of Windows. An app can browse files or open documents normally, but installing a driver or changing protected settings requires another key.

Key features:

• Permission prompts: Windows asks before an app receives administrator access.
• Standard account protection: Someone without administrator rights must enter an administrator’s credentials.
• Secure desktop: The screen dims during many prompts so other apps can’t easily interfere with your response.
• Four notification levels: You can choose how often Windows asks for approval.
• System-wide coverage: UAC applies to Windows settings, desktop programs, installers, and drivers.

UAC is built into Windows 10 and Windows 11. macOS uses its own administrator-password and permission system, so these steps don’t apply to a Mac.

What Triggers a UAC Prompt?

You’ll usually see a UAC prompt when an action needs administrator permission. Common examples include:

• Installing or uninstalling desktop software
• Installing drivers
• Running an app as administrator
• Adding or removing user accounts
• Changing UAC settings
• Editing protected files inside the Windows or Program Files folders
• Changing Windows Firewall settings
• Modifying system-wide configuration through Registry Editor
• Opening certain administrative tools

A prompt doesn’t automatically mean an app is dangerous. It means the app wants broad access, so you should check its name and publisher before approving it.

If you didn’t start the action, select No. That’s UAC doing its job.

Understanding the Four UAC Levels

Windows 10 and Windows 11 use the same four-level slider. The default setting gives you a sensible balance between protection and interruptions.

UAC level	What happens	Best fit
Always notify	Windows asks when apps or you change protected settings. The desktop dims.	PCs where tighter control matters more than convenience
Notify me only when apps try to make changes to my computer (default)	Windows asks when apps request administrator access. The desktop dims.	The best choice for everyday use
Notify me only when apps try to make changes to my computer (do not dim my desktop)	Prompts appear without switching to the secure desktop.	PCs where dimming causes display or accessibility trouble
Never notify	Windows stops showing UAC prompts through the normal slider interface.	Short-term troubleshooting only

The third level looks convenient, but disabling the secure desktop removes part of UAC’s protection. I’d only use it when screen dimming causes a real problem.

Before You Change UAC

Make sure you have:

• An administrator account
• Any open work saved
• The name and publisher of the app causing repeated prompts
• Time to restart if you use an advanced method

Warning: Keeping UAC enabled reduces the damage malware and ransomware can cause. Try lowering the notification level or fixing the troublesome app before switching UAC off across the entire PC.

How to Change UAC Settings in Windows 10 and Windows 11

The Control Panel slider is the safest and easiest method. It adjusts the prompts without completely removing the underlying UAC system.

Step 1: Open Control Panel

Open Start, type Control Panel, and select Control Panel from the search results.

Step 2: Open User Accounts

Set View by to Large icons or Small icons, then select User Accounts.

Step 3: Open the UAC Controls

Select User Accounts again if Windows shows a category page. Then select Change User Account Control settings.

Step 4: Choose a Notification Level

Move the slider to the level you want. For fewer interruptions without fully switching UAC off, choose the third level.

Select OK, then approve the prompt. The new notification setting should take effect immediately.

To restore the recommended setting, repeat these steps and move the slider to Notify me only when apps try to make changes to my computer (default).

How to Disable UAC Using Command Prompt

The slider’s Never notify option suppresses prompts, but Windows may retain some underlying UAC behavior. Changing EnableLUA to 0 disables Admin Approval Mode and more of UAC’s supporting behavior.

This can break certain apps and Windows features. Use it only for a specific testing or compatibility problem, and switch UAC back on afterward.

Step 1: Open Command Prompt as Administrator

Open Start, type cmd, and select Run as administrator beside Command Prompt. Select Yes when UAC asks for approval.

Step 2: Disable UAC

Enter the following command and press Enter:

reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f

A successful result displays The operation completed successfully.

Step 3: Restart Your PC

Save your work, open Start > Power, and select Restart. The registry change won’t fully apply until Windows restarts.

Turn UAC Back On

Open Command Prompt as administrator and run:

reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 1 /f

Restart the computer again. Windows will restore its underlying UAC behavior, including the notification level selected in Control Panel.

How to Disable UAC Using Group Policy

Local Group Policy Editor is included with Windows Pro and Enterprise editions. Windows Home users should stick with the Control Panel method unless a specific problem requires the registry method.

Step 1: Open Local Group Policy Editor

Open Start, type Edit group policy, and select Edit group policy.

Step 2: Open Windows Settings

In the left pane, expand Computer Configuration, then expand Windows Settings.

Step 3: Open Security Options

Expand Security Settings > Local Policies, then select Security Options.

Step 4: Open the Admin Approval Mode Policy

Double-click User Account Control: Run all administrators in Admin Approval Mode.

Step 5: Disable the Policy

Select Disabled, then select OK. Restart Windows so the policy can take effect.

Group Policy also includes separate controls for administrator and standard-user elevation prompts. Those settings are useful on managed work PCs, but changing them can lock users out of administrative tasks. If your employer manages the computer, leave these policies alone and contact whoever handles its Windows settings.

How to Disable UAC Using Registry Editor

Registry Editor provides the same EnableLUA change as the Command Prompt method, but you make it through menus. A wrong registry edit can cause some spectacular Windows weirdness, so check the path carefully.

Step 1: Open Registry Editor

Press Windows + R, type regedit, and select OK. Approve the UAC prompt.

Step 2: Open the System Policy Key

Paste this path into Registry Editor’s address bar and press Enter:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

Confirm that System is selected in the left pane.

Step 3: Change EnableLUA

Double-click EnableLUA in the right pane. Set Value data to 0, leave Base set to Hexadecimal, and select OK.

Step 4: Restart Windows

Close Registry Editor and restart the PC. UAC’s underlying protections remain disabled until you change EnableLUA back to 1 and restart again.

Safer Ways to Handle Repeated UAC Prompts

A noisy app is usually the problem, so changing the whole security system is a pretty big hammer. Try these options first:

• Keep the default level: It blocks surprise elevation attempts without asking about every Windows setting you change.
• Check the app’s publisher: On the UAC prompt, confirm that Verified publisher names a company you recognize.
• Update or reinstall the app: A damaged or poorly configured installation can request administrator access every time it starts.
• Run as administrator only when needed: Right-click the app and select Run as administrator for that one session.
• Use a standard account daily: Windows can request an administrator password when a protected action is necessary.
• Fix remote-support access: Choose a remote-support tool that can handle UAC prompts instead of disabling UAC across the PC.

For managed business computers, application-control tools such as AppLocker or Windows Defender Application Control can restrict which programs run. Those tools need careful setup and are overkill for a typical home PC.

Tips and Troubleshooting

The Yes Button Is Missing or Grayed Out

Your account probably doesn’t have administrator access, or a policy is blocking elevation.

1. Open Settings > Accounts > Your info.
2. Check whether Administrator appears beneath your account name.
3. Sign in with an administrator account if yours is a standard account.
4. Ask your workplace administrator for help if the PC is managed.

Don’t try to work around an organization-controlled policy. It may be protecting company files or required software.

UAC Still Appears After Selecting Never Notify

On some managed, server, or enterprise systems, the slider controls prompts without disabling every part of UAC. Group Policy can also override your local choice.

Restart the computer first. If the setting returns after rebooting, a management policy is probably restoring it.

Apps Stop Working After Disabling UAC

Some Windows features and apps depend on UAC-related behavior. Set EnableLUA back to 1, restart the PC, and use the normal slider to reduce prompts instead.

This is one reason the registry method belongs at the bottom of the toolbox.

A UAC Prompt Appears for an App You Don’t Recognize

Select No, close the app, and run a scan with Windows Security:

1. Open Start, type Windows Security, and open the result.
2. Select Virus & threat protection.
3. Select Quick scan.
4. Wait for Windows Security to report the result.

UAC can’t tell whether every app is trustworthy. It gives you a chance to stop the change before it happens.

You Can’t Control a UAC Prompt Remotely

The prompt may be running on the secure desktop, which some remote-support tools can’t control. Configure the remote tool to support elevated sessions or start it with administrator rights before connecting.

Turning off UAC for remote support trades one inconvenience for a much larger security gap. I’d skip that fix unless the PC is isolated and you’re performing a short, controlled test.

UAC Settings at a Glance

Task	Recommended method	Restart required
Change how often prompts appear	Control Panel slider	Usually no
Stop normal UAC notifications	Select Never notify	Usually no
Fully change EnableLUA behavior	Command Prompt or Registry Editor	Yes
Manage UAC on Windows Pro or Enterprise	Local Group Policy Editor	Yes
Restore UAC protection	Set EnableLUA to 1	Yes

Should You Disable UAC?

For an everyday Windows PC, keep UAC enabled at its default level. The occasional prompt is annoying, but it puts a useful checkpoint between an app and the parts of Windows that can affect every user.

If lowering the slider solved the interruptions, you can keep working without removing the entire safety net. Save the command, registry, and policy methods for short troubleshooting sessions where you’ve identified the exact app causing trouble.
