Windows is not recognizing the built-in or external camera. Microsoft says this error is commonly associated with missing, outdated, or corrupted camera drivers, although detection and hardware connection should also be verified before assuming the camera itself has failed.

First action

Verify detection before changing more settings

Run DeviceOK's webcam test and check Windows camera detection first. If Windows also cannot see the camera, continue with Microsoft's camera troubleshooter and official driver update path.

Safe sequence

What to check next

1
Check for a physical privacy shutter, camera switch, or disabled camera key.
2
Confirm whether the camera appears in Device Manager under Cameras or Imaging devices.
3
Use Windows Update or the device maker's official support page for camera driver updates; do not download drivers from third-party mirrors.
4
If another app can use the camera, treat the problem as app-specific rather than a total camera detection failure.

Retest

Know whether the change worked

After each meaningful change, run the DeviceOK webcam test again. If DeviceOK receives video but one application still fails, move to that application's camera selection and permission path.
