Can't reinstall Windows camera.

For Windows 10, try these steps in order:

1. Restart the PC fully Select Start > Power > Restart. Do a full restart, not sleep or hibernate.
2. Check Windows Update and optional driver updates Go to Start > Settings > Windows Update > Check for updates. If nothing appears for the camera, go to Advanced options > Optional updates and install any camera-related driver updates, then restart.
3. Run the Windows camera troubleshooter On Windows 10, start with the automated camera troubleshooter in the Get Help app. If needed, use Start > Settings > Update & security > Troubleshoot > Camera > Run the troubleshooter.
4. Reinstall the camera driver in Device Manager Since the camera was already uninstalled, force Windows to detect it again:
   • Open Device Manager.
   • Look under Cameras, Imaging devices, or Sound, video and game controllers.
   • If the camera appears, right-click it and select Update driver > Search automatically for drivers.
   • If it does not appear, select Action > Scan for hardware changes.
   • Restart the PC and test the Camera app again.
5. If the camera appears but still fails, uninstall and reinstall the driver cleanly
   • In Device Manager, right-click the camera > Properties.
   • Open the Driver tab.
   • Select Uninstall Device.
   • If available, select Delete the driver software for this device or Attempt to remove the driver for this device.
   • Select OK.
   • In Device Manager, select Action > Scan for hardware changes.
   • Restart the PC.
6. If this is an external USB webcam, try a different USB port Then open Device Manager and run Action > Scan for hardware changes again.
7. If this is a USB webcam, switch it to the in-box UVC driver This can help when the manufacturer driver is the problem. Admin rights are required, and some features such as Windows Hello face recognition may stop working with the UVC driver.
   • Open Device Manager.
   • Find the webcam under Cameras or Imaging devices.
   • Right-click it > Update driver.
   • Select Browse my computer for drivers.
   • Select Let me pick from a list of available drivers on my computer.
   • Select USB Video Device > Next.
8. Check whether antivirus or firewall software is blocking camera access Some security software can lock the camera. Temporarily disable or pause protection in the antivirus or firewall app, test the camera, then re-enable protection.
9. If the camera stopped working after a Windows update, roll back the driver In Device Manager > camera Properties > Driver tab > Roll Back Driver. Restart after the rollback.

If the camera still does not return in Device Manager or still cannot be used after these steps, the next supported path in the provided guidance is to check the camera manufacturer’s support site for the correct driver or device-specific help.
