Camera doesn't work in Windows

If your camera stops working, it can disrupt video calls, online meetings, and other activities that rely on camera. Common causes include missing drivers after a recent update, antivirus software blocking the camera, restrictive privacy settings, or issues with the app you're trying to use. This article provides a step-by-step guide to help you troubleshoot and resolve camera problems effectively.

Run the Windows camera troubleshooter

If you are using a Windows 11 device, start by running the automated camera troubleshooter in the Get Help app. It will automatically run diagnostics and attempt to fix most camera problems. If you are using an older version of Windows or a mobile device, please skip to General troubleshooting steps.

If the Camera troubleshooter in Get Help app is unable to resolve your issue, select your specific Camera problem from the Most common camera problems section below and follow the provided steps. If your issue is not listed, try the possible solutions listed.

General troubleshooting

Please try the following general troubleshooting steps to help solve the camera problem.

Step 1. Ensure that the camera is connected

• If you're using an external camera, ensure it is securely connected to the USB port. Check for any loose cords or cables and confirm all connections are properly plugged in.
• To rule out hardware issues, test the camera on a different device.

Step 2. Check for a camera switch or a button on your device

Some laptops and portable devices have a physical switch or button that turns the camera on or off. When it's turned off, your device may not recognize that there's a camera installed, or it may cause your camera to show an image of a camera with a slash through it. If your laptop has a switch or button, make sure it's in the on position before using your camera.

Those switches or buttons may not be easy to find, so make sure you check all possible places. For example, it could be:

• A button on the keyboard that's activated with the Fn key
• A dedicated camera button on the keyboard
  
• A sliding switch on the side of a laptop
  
• A small slider for a shutter, built right into the camera
  

Step 3. Allow your apps to access the camera

If you recently updated Windows 11, you might need to give apps permission to use the camera. In newer versions of Windows 11, some apps won't have default access to the camera. 

Here's how to let your apps access the camera:

1. Select Start > Settings > Privacy & security > Camera .

   Allow access to the camera on this device

2. Make sure Camera access is turned on.

   Note

   If camera access for the device is turned off and greyed out, you'll need an administrator on the device to turn on camera access for you.

3. Make sure Let apps access your camera is turned on.

4. Choose which apps should have access. Only apps that were installed from the Microsoft Store will appear in this list.

If you're having problems with an app that you did not install from Microsoft Store, make sure that Let desktop apps access your camera is turned on. You can't turn off camera access for individual desktop apps. Internet browsers, like Microsoft Edge, and many video conferencing apps, like Microsoft Teams, are desktop apps that require this setting to be turned on.

For more information, visit Manage app permissions for camera in Windows.

Step 4. Test your camera in a different app

Use the Camera app in Windows to check if the issue is specific to a certain app.

• Open Start > Camera and see if the preview works.
• If the camera works in one app but not another, the issue lies with the app settings.

Step 5. Check for Windows update

• Check for updates. Select Start > Settings > Windows Update > Check for updates.

  • If there are no updates for your camera, try to select Advanced options > Optional updates, and look for any driver updates for your camera. Allow available updates to install, then restart your device when it's ready.

• Restart your PC. If you haven't restarted your device since the camera stopped working, you should do so. Select Start > Power > Restart . Waking up your device from sleep isn't the same thing as a restart.

• Test your camera with the Camera app. Select Start , then choose Camera from your apps. If you're asked to allow access to the Camera, select Yes. If the camera works in the Camera app, the problem might be with the app you're trying to use. 

  Open Camera

Step 6. Run the camera troubleshooter

The camera troubleshooter might be able to fix camera problems automatically. To run the troubleshooter:

1. Select Start > Settings > System.
2. Scroll down and click Troubleshoot, then select Other troubleshooters.
3. Locate the Camera section and click the Run button to launch the camera troubleshooter

Step 7. Check your antivirus software

Some antivirus programs or firewalls might block camera access. Look for that settings and temporarily disable them and test your camera. For help, visit your antivirus software company’s website.

Step 8. Check your hardware drivers

Try a different USB port and scan for hardware changes:

If you're using an external camera, try using it with a different USB port on your device first. If that doesn't work, or your camera is built in on your device, try this: 

1. Select Start , type device manager, then select it from the search results.
2. Find your camera under Cameras, Imaging devices, or Sound, video and game controllers.
3. If you can't find your camera, select the Action menu, then select Scan for hardware changes.
4. Wait for it to scan and reinstall updated drivers, restart your device, then open the Camera app again to test it.
5. If these steps don't fix your issue, continue to the next steps.

Roll back the camera driver:

If your camera stopped working after an update, try these steps:

1. In Device Manager, right-click (or press and hold) on your camera, then select Properties.
2. Select the Driver tab, select Roll Back Driver, and then choose Yes. (Some drivers don’t provide this option. If your driver doesn’t have Roll Back Driver available, go ahead to the next fix.)
3. After the roll back is complete, restart your device, and then try opening the Camera app again.
4. If rolling back didn’t work or isn’t available, continue to the next steps.

Uninstall your camera driver and scan for hardware changes:

1. In Device Manager, right-click (or press and hold) on your camera, and then select Properties.
2. Select the Driver tab, then select Uninstall Device. Select the check box for Attempt to remove the driver for this device, then select OK.
3. In Device Manager, on the Action menu, select Scan for hardware changes.
4. Wait for it to scan and reinstall updated drivers, restart your PC, and then try opening the Camera app again.

Switch external USB camera to use UVC driver:

Most available USB webcams are UVC (standard USB Video Class) compatible cameras. They will work with the UVC driver that is included in Windows (the in-box UVC driver). If your webcam is not working correctly, swapping to the in-box UVC driver may resolve the issue. Please follow the steps below to change drivers (admin rights are required).

1. Select Start , type device manager, then select it from the search results.
2. Find the problem webcam from the list of devices shown in the Device Manager. It should appear either under Cameras or Imaging devices.
3. Right-click the webcam device and select Update driver.
4. Select Browse my computer for drivers.
5. Select Let me pick from a list of available drivers on my computer.
6. Select USB Video Device and then select Next to complete the driver update.
7. Select Close to acknowledge settings choices and go back to Device Manager. The webcam will now appear under the Cameras category in the Device Manager list.
