Windows camera error

0xA00F4244 NoCamerasAreAttached

Windows is not detecting the camera. Microsoft classifies 0xA00F4244 as a camera-detection error, so detection, privacy switches, drivers and the physical connection should be checked before assuming the camera sensor itself has failed.

Verify detection before changing more settings

Run DeviceOK's webcam test and check whether Windows sees the camera. If neither Windows nor the browser can see it, continue with Microsoft's camera troubleshooter and the device maker's official driver path.

Safe sequence

What to check next

  1. 1

    Check a physical privacy shutter, camera switch or disabled camera key.

  2. 2

    Look for the camera in Device Manager under Cameras or Imaging devices.

  3. 3

    Use Windows Update or the device maker's official support page for camera drivers; avoid third-party driver mirrors.

  4. 4

    If another app can use the camera, treat the problem as app-specific rather than total camera 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.
