Camera is not working

Establish the scope

Compare the built-in Camera app with the original calling app after closing other camera users. If Camera works, inspect selection and permission in the failing app. If every app fails, check the shutter, camera key, privacy controls, and device status before assuming a hardware fault.

Apply the safer fix first

Enable camera and per-app access. Windows 11 uses Settings > Privacy & security > Camera; Windows 10 uses Settings > Privacy > Camera. Close conferencing and browser apps completely, then select the correct camera.

Investigate the cause

Inspect Cameras or Imaging devices in Device Manager, since the class can vary by hardware and driver, and use the PC maker driver. If Camera works, reset only the affected app selection.

Protect the recovery path

Enable access only for apps you intend to use. Stop for managed restrictions; do not bypass privacy controls or install drivers from an unknown download site.

Verification

• Open the Camera app and confirm a live image from the intended camera.
• Close it before testing the original calling app, then confirm that app uses the same camera.

When to stop

Do not continue with broader resets when the camera remains absent after appropriate connection and driver checks, physical damage is present, or managed policy blocks it. Preserve the observations already collected and use the device maker, network administrator, Microsoft support, a qualified repair technician, or data-recovery help according to the evidence.

Review the safe troubleshooting workflow before any broader recovery step.
