Block Metro Apps From Using Your Webcam in Windows

This guide shows you how to stop Windows Store (Metro/UWP) apps from accessing your webcam, either entirely or on a per-app basis. You’ll control these settings through Windows’ built-in privacy panel, so no third-party software is needed. The steps work for Windows 10 and Windows 11, though the exact menu names differ slightly.

What You’ll Need

• A PC running Windows 10 or Windows 11 with a webcam (built-in or USB).
• An administrator account (required to change settings for all users).
• Knowledge of which apps you want to block—you can block all or pick specific ones.

Step-by-Step

1. Open Windows Settings. Press Windows + I on your keyboard. This opens the Settings app.
2. Go to Privacy & Security. In Windows 11, click “Privacy & security” in the left sidebar. In Windows 10, click “Privacy” (it’s a direct option).
3. Select Camera. Under the “App permissions” section (Windows 10) or “App permissions” (Windows 11), click “Camera”. This opens the camera privacy settings.
4. Block all camera access (optional). At the top, you’ll see “Camera access”. Toggle it to Off. This disables the webcam for all apps and the system itself. If you only want to block Metro apps, leave this On and continue.
5. Block desktop apps (optional). Below that, there’s “Let desktop apps access your camera”. Toggle it Off to block traditional desktop programs. This does not affect Metro apps, but it’s a useful extra layer.
6. Block all Metro apps. Find “Let apps access your camera” (Windows 10) or “Let apps access your camera” (Windows 11). Toggle it to Off. This instantly blocks every Microsoft Store app from using the webcam.
7. Block specific Metro apps. If you want to keep some apps working, leave the master toggle On, then scroll down to the list of apps under “Choose which apps can access your camera”. Toggle Off the specific apps you want to block (e.g., Camera, Skype, Zoom).
8. Verify the change. Close Settings and open the app you blocked. It should show an error like “Camera can’t be found” or a black preview. If it still works, you may need to restart the app or your PC.

Common Mistakes

• Toggling the wrong master switch. The top “Camera access” turns off the camera for everything, including Windows Hello. If you only want to block Metro apps, leave that On and toggle “Let apps access your camera” Off.
• Forgetting that desktop apps are separate. The “Let desktop apps access your camera” is a different toggle. If you only block Metro apps, traditional programs like Chrome or OBS can still use the webcam.
• Not restarting the app. Some apps check the setting only when they start. If you change the setting while the app is running, it may keep using the camera until you close and reopen it.
• Assuming the setting applies to the system camera. Blocking Metro apps does not stop Windows Hello face recognition or the Camera app from working—those are system-level. If you want to disable the webcam entirely, use Device Manager.

Tips

• Use Device Manager for a hard block. If you want to physically disable the webcam so no software can use it, open Device Manager, find “Cameras”, right-click your webcam, and choose “Disable device”. This works for all apps, Metro or not.
• Check the per-app list regularly. Newly installed Metro apps default to “On” for camera access. After installing a new app, revisit the Camera privacy settings to adjust its permission.
• Use the same steps for the microphone. The privacy panel has a similar “Microphone” section. You can apply the same logic to block mic access.
• Know your Windows version. In Windows 10, the settings are under “Privacy” > “Camera”. In Windows 11, it’s “Privacy & security” > “Camera”. The toggles are identical.

Troubleshooting

If you’ve followed the steps but an app still uses the camera, try these in order:

1. Restart the app. Close it completely (check the system tray) and reopen it.
2. Restart your PC. A reboot ensures the settings take effect system-wide.
3. Check if the app is a desktop app. Some apps that look like Metro apps (e.g., Skype from the Store) are actually desktop apps. Ensure the “Let desktop apps access your camera” toggle is Off.
4. Update Windows. Go to Settings > Windows Update and install any pending updates. Bugs in the privacy settings have been fixed in cumulative updates.
5. Check Group Policy (Pro/Enterprise only). If you’re on Windows Pro or Enterprise, a Group Policy setting might override the privacy toggles. Press Win + R, type gpedit.msc, and navigate to Computer Configuration > Administrative Templates > Windows Components > App Privacy. Look at “Let Windows apps access the camera”. If it’s “Enabled” and set to “Force Off”, that’s the cause. Set it to “Not Configured” or “Enabled” with “Force On” to allow the Settings to work.
6. Check the camera’s own privacy shutter. Some laptops have a physical shutter or a function key (e.g., F10) that disables the camera. Make sure it’s not engaged.

Frequently Asked Questions

Will blocking Metro apps affect Windows Hello face sign-in?

No. Windows Hello uses a separate system-level camera driver and is not controlled by the “Let apps access your camera” toggle. If you want to disable Windows Hello, you must turn off the top “Camera access” switch or disable the camera in Device Manager.

Can I block the camera for a specific user account?

Yes, but only if you’re an administrator. The privacy settings are per-user. Log into the account you want to restrict, follow the steps, and the changes apply only to that account. Other accounts remain unaffected.

Why does the Camera app still work after I blocked Metro apps?

The Camera app is a system app and is exempt from the “Let apps access your camera” toggle in some Windows versions. To disable it, you’d need to turn off the master “Camera access” switch or disable the camera in Device Manager.

Do these settings apply to third-party apps like Zoom or Skype?

Yes, if they are installed from the Microsoft Store, they are considered Metro apps and will be blocked. However, if you installed them from the web (desktop versions), they are desktop apps and require the separate desktop toggle to be turned off.

Is there a way to block the camera temporarily?

Yes. You can toggle “Let apps access your camera” off when you don’t need it and on when you do. This is faster than going through Device Manager. Alternatively, use a physical camera cover.

What if I don’t see the “Camera” option in Settings?

That means Windows doesn’t detect a camera. Check Device Manager under “Cameras” or “Imaging devices”. Reinstall the camera driver from the manufacturer’s website, or if it’s a USB camera, try a different port.
