Please refer suggestions in this support article: https://support.microsoft.com/en-us/windows/camera-doesn-t-work-in-windows-32adb016-b29c-a928-0073-53d31da0dad5

Answer 2

Most camera issues can be due to a physical privacy cover covering the lens. Make sure that's not the case.

Otherwise there is usually a physical button/key/switch you can use to turn the camera on or off. For example, most Lenovo uses F8 or Fn+F8, or a switch above the lens, HP has a camera key or a button on the side of the laptop, MSI uses F6 or Fn+F6, etc.

If you are not sure, please hold down Windows + R keys, type in msinfo32.exe and hit enter. Then share a screenshot of the System Information window. Thanks!

Error code 0xA00F42B2 indicates a camera problem that can often be resolved by checking privacy settings, closing conflicting apps, and verifying drivers.

Follow these steps on Windows 11:

1. Close apps that might be using the camera
   1. Close all apps that could be using the camera (Teams, Zoom, browsers, etc.).
   2. Right‑click the taskbar and select Task Manager.
   3. In Processes, look for any app that might be using the camera, right‑click it, and select End task.
2. Check camera privacy permissions
   1. Select Start > Settings > Privacy & security > Camera.
   2. Make sure Camera access is turned on.
      • If it is off and greyed out, an administrator must turn it on.
   3. Make sure Let apps access your camera is turned on.
   4. In the list of apps, ensure the specific app being used has camera access enabled.
3. Test the camera in the built‑in Camera app
   1. Select Start > Camera.
   2. Check if the preview works.
   3. If the camera works here but not in another app, adjust that app’s own camera settings.
4. Check Windows Update and restart
   1. Select Start > Settings > Update & Security > Windows Update > Check for updates.
   2. If View optional updates appears, open it and install any camera‑related updates.
   3. Restart the PC (do a full Restart, not just wake from sleep).
   4. Test again with the Camera app.
5. Reinstall or switch the camera driver
   1. Open Device Manager (search for “device manager” from Start).
   2. Under Cameras or Imaging devices, right‑click the camera and select Properties.
   3. Go to the Driver tab and select Uninstall Device.
   4. Check Delete the driver software for this device, then select OK.
   5. In Device Manager, open the Action menu and select Scan for hardware changes.
   6. After it reinstalls the driver, restart the PC and test the Camera app.
   If the webcam is USB and still not working correctly, switch to the in‑box UVC driver:
   1. In Device Manager, right‑click the webcam and select Update driver.
   2. Select Browse my computer for drivers.
   3. Select Let me pick from a list of available drivers on my computer.
   4. Select USB Video Device and then Next.
   5. Close Device Manager and test the camera again.
   • Note: The in‑box UVC driver may not support all camera features (for example, Windows Hello face recognition may stop working if it relied on the manufacturer’s custom driver).
6. Check antivirus or firewall
   1. Open the antivirus or security suite.
   2. Look for any camera/webcam protection feature and temporarily disable it.
   3. Test the camera again. If it works, adjust the antivirus settings to allow camera access.

If the camera still does not work after these steps, check the camera manufacturer’s support site for model‑specific drivers or diagnostics, and test the camera on another device to rule out hardware failure.
