Try these checks in order:
- Check camera permissions in Windows 11.
- Go to Start > Settings > Privacy & security > Camera.
- Turn Camera access to On.
- Turn Let apps access your camera to On.
- Turn Let desktop apps access your camera to On.
- This is important because desktop apps such as browsers and video conferencing apps may not appear clearly in the app list.
- Close apps that commonly hold the camera.
- Close apps such as video meeting apps, the Camera app, and browser windows or tabs that may be using the camera.
- If using a browser, close other tabs that might be accessing the camera.
- Check for background apps.
- Press Ctrl + Shift + Esc to open Task Manager.
- Look for apps like Teams, Skype, Zoom, OBS, or browser processes.
- End only apps that may be using the camera, then test the camera again.
- Run the automated camera troubleshooter.
- Open the Get Help app and run the camera troubleshooter. It automatically runs diagnostics and takes the correct steps to fix most camera issues.
- Verify the camera works in Windows settings and apps.
- In Settings > Privacy & security > Camera, confirm the needed app is allowed.
- Note that some desktop apps might still use the camera even if they do not appear in the list.
- If this is a Surface device, check updates in the Surface app.
- Open the Surface app.
- Expand Help & support to check update status.
- If updates are available, select Check for updates and install them.
- If this is a Surface and the issue continues, reinstall the camera driver.
- Warning: Do not do this on Surface Pro X. On that device, uninstalling drivers can require a full system reset to restore them.
- Open Device Manager.
- Expand Cameras.
- Double-click the camera, open the Driver tab, and select Uninstall Device.
- Select Attempt to remove the driver for this device and then Uninstall.
- Restart the device.
Also note:
- If Windows Hello is used for sign-in, it can still access the camera even when Camera access is turned off.
- Some apps open the Camera app to take photos or video, so the app using the camera may not appear directly in the list.
