What You’ll Need

• A Windows 10 or Windows 11 PC with administrator privileges
• Stable internet connection (for updates and troubleshooting tools)
• Optional: External webcam or camera device if your integrated camera is faulty

Step-by-Step

1. Restart Your Computer
   Begin with a simple restart. Sometimes, temporary glitches can cause camera errors. Save your work and restart your PC to see if the issue resolves itself.
2. Check Camera Permissions
   Ensure the Camera app has permission to access your camera. Go to Settings > Privacy & security > Camera. Make sure Allow apps to access your camera is turned on, and scroll down to verify the Camera app has permission.
3. Update Windows
   Keeping Windows up to date ensures compatibility and bug fixes. Navigate to Settings > Update & Security > Windows Update and click Check for updates. Install any available updates and restart your PC.
4. Update Camera Drivers
   Faulty or outdated drivers can cause camera errors. Open Device Manager (right-click Start button and select it). Locate Imaging Devices or Cameras, right-click your camera device, and select Update driver. Choose Search automatically for drivers and follow prompts. If updates are found, install them and restart your PC.
5. Reset the Camera App
   Corrupted app data can cause errors. Go to Settings > Apps > Installed apps. Find the Camera app, click it, then select Advanced options. Click Reset to restore the app to default settings. Confirm if prompted.
6. Reinstall the Camera App
   If resetting doesn’t work, reinstall the Camera app. In PowerShell (run as administrator), type:

   Get-AppxPackage *Microsoft.WindowsCamera* | Remove-AppxPackage

   Then, reinstall via the Microsoft Store or by running:

   Get-AppxPackage -allusers Microsoft.WindowsCamera | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

   Restart your computer afterward.

7. Check for Conflicting Software
   Some third-party security or webcam software can interfere with the Camera app. Temporarily disable or uninstall any such software and test if the camera works.
8. Run the Hardware Troubleshooter
   Windows includes a troubleshooter for hardware issues. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters. Select Camera and click Run the troubleshooter. Follow the prompts and apply recommended fixes.
9. Check for External Hardware Issues
   If you’re using an external webcam, ensure it’s properly connected. Try plugging it into a different USB port or testing it on another device. If it doesn’t work elsewhere, the hardware may be faulty.
10. Perform a System File Check
    Corrupted system files can cause various errors. Open Command Prompt as administrator and run:

    sfc /scannow

    Wait for the scan to complete and follow any instructions to fix detected issues. Restart your PC afterward.
