To turn on User Account Control (UAC) [in Windows or change](https://www.winsolvetech.com/security-features-windows-11/) how often it asks for permission, open the UAC settings panel, move the slider to the level you want, and save the change. UAC helps protect your PC by prompting before programs or settings make system-level changes, and you can set it high enough to improve security without making normal work miserable. After you save it, confirm that Windows still shows prompts for app installs and admin actions.

## What UAC does before you change anything

UAC is Windows' built-in approval check for actions that affect the whole system, not just one app. If a program wants to install software, change protected settings, or make a change that needs administrator rights, UAC can pause and ask you to allow it first.

That matters because many unwanted changes start with a simple click. A malicious attachment, a fake installer, or a tool you meant to try for one minute can all try to make system changes. UAC gives you a chance to stop and think before those changes happen.

Before you start:

- You’re signed in with an account that can approve changes, usually an administrator account.
- You know where to find Settings or Control Panel.
- You’re ready to accept a prompt or enter an administrator password if Windows asks for it.

## Open the UAC settings panel

You can reach UAC settings from either the Start menu or Control Panel. The fastest [path on most Windows](https://www.winsolvetech.com/understanding-windows-security-hub/) versions is through Start search.

1. Open the Start menu and type `UAC`.
2. Select **Change User Account Control settings** from the results.
3. If Windows opens a Control Panel page, you’re in the right place. You should see a vertical slider with four levels.

If search doesn’t bring it up, use Control Panel instead.

1. Open **Control Panel**.
2. Choose **User Accounts**.
3. Select **User Accounts** again if needed.
4. Click **Change User Account Control settings**.

You should now see the UAC slider and a short description for the selected level.

### What the slider levels do

The four slider [positions control when Windows](https://www.winsolvetech.com/customize-windows-defender-settings/) asks for permission:

- **Always notify**: Windows asks before any app makes changes and before you change Windows settings. This is the strictest setting and can feel noisy.
- **Default level**: Windows asks when apps try to make changes, but it is less intrusive than the top setting. For many people, this is the best balance between security and convenience.
- **Notify me only when apps try to make changes**: Windows reduces prompts for some Windows changes. This can be easier to live with, but it gives you fewer checks.
- **Never notify**: Windows does not ask for UAC approval. This removes the protection UAC provides and is the least safe choice.

If you want better security without constant interruptions, start with the default level. Move up if you want more protection on a shared or sensitive PC. Move down only if the prompts are getting in the way of work and you still want UAC active.

## Click OK and confirm the prompt

1. Drag the slider to the level you want.
2. Click **OK**.
3. If Windows asks for confirmation, approve it with **Yes** or enter the administrator password.

If the change applies, Windows closes the settings window and keeps the new level. If it asks for admin approval and you cancel, the setting stays where it was.

After saving, open the UAC panel again if you want to double-check the slider position. That gives you a quick visual confirmation that the change stuck.

If you want one more check, look for a prompt the next time you run something that needs permission. The presence of the prompt is the clearest sign that UAC is active.

## What changes you’ll notice after setup

Once UAC is on, you should expect prompts whenever an app or task tries to make protected changes. That can happen during software installs, driver updates, changes to system settings, or tools that need admin rights to run properly.

You may also see prompts when you open certain control tools or management consoles. That does not mean something is wrong. It usually means Windows is protecting a setting that affects all users or the operating system itself.

A few common examples include:

- Installing or uninstalling desktop software
- Changing security-related system settings
- Running a program as administrator
- Allowing an app to make system changes after an update

If a prompt appears for something you trust and expect, approve it. If it appears unexpectedly, stop and check the app name and publisher before allowing it.

You may also notice the screen dimming before the prompt appears. That is normal on many systems and is part of how Windows keeps the prompt separate from the rest of the desktop.

## When to choose a stricter or looser setting

Pick the strictest level you can live with, not the strictest one available.

A family PC that gets used by different people usually benefits from a stricter setting, because it gives more chances to stop accidental installs and questionable downloads. A work laptop often does best with the default level, since that catches admin-level changes without getting in the way of routine work.

If you mostly use trusted software and you rarely install new tools, you can choose a stricter level without much pain. If you install printers, developer tools, or business apps often, the default level is usually easier to live with.

The best setting is the one you’ll keep. A slightly lower setting that stays enabled is better than a strict setting you end up turning off.

If the prompts are only annoying because one app keeps asking for approval, deal with that app first. Sometimes it needs an update, a repair, or a different way of launching it. Lowering UAC one step is better than turning it off for the whole PC.

## How to tell whether UAC is working

The simplest check is to open something that should require permission. For example, try changing a system setting that normally needs admin approval, such as a protected Windows option or a tool that says it will make changes to the device.

If UAC is working, Windows should show a prompt asking for approval or a password. On many systems, the screen may dim while that prompt is open. If you see the prompt, the setting is active.

You can also return to the UAC settings panel and confirm the slider is still at the level you chose. That tells you the change was saved, but the prompt test tells you the feature is actually doing something.

For a practical check, try a task that normally asks for admin rights, such as starting an installer or opening a management tool. If Windows asks before it continues, UAC is doing its job.

## If UAC feels too annoying

If the prompts get old, move the slider down one step before you turn UAC off. That usually reduces the interruptions without removing the protection completely.

If a single app keeps asking for approval, check whether it can be updated, repaired, or run in a different way. Sometimes the app is simply built to request admin rights too often. In that case, lowering UAC a little is safer than disabling it across the whole PC.

Turning UAC off entirely is risky because it removes one more barrier between you and silent system changes. That can make it easier for unwanted software to modify Windows without a clear warning.

## Common mistakes people make with UAC

A common mistake is treating UAC like antivirus. It is not the same thing. Antivirus looks for malicious files and behavior; UAC asks for approval before privileged changes happen.

Another mistake is turning UAC off just to stop one annoying app from prompting. That fixes the symptom, not the cause, and it weakens protection for everything else on the machine.

People also expect UAC to block all malware by itself. It can help by forcing prompts, but it is not a complete safety net. You still need to be careful about what you install, what you open, and which prompts you approve.

If you change the setting, save it, and later feel the prompts are too frequent, adjust the slider one notch rather than abandoning it altogether.

## Conclusion

Once UAC is set at a level you can live with, leave it there and use the prompts as a checkpoint, not an annoyance. If you install software often, stay near the default. If you want tighter control on a shared or sensitive PC, move up one level. The key is to keep it on, verify that it prompts, and adjust only as much as you need.
