How to get Windows Hello to work on a new Windows 11 laptop; the error is "couldn't turn on camera".

To resolve the issue with Windows Hello facial recognition not turning on the camera, you can follow these troubleshooting steps:

1. Check Virtualization Based Security (VBS): Ensure that VBS is running. Open System Information and check if Virtualization Based Security is listed as Running.
2. Verify Biometric Isolation Trust-lets: Check if the biometric isolation trust-lets are running. In System Information, under Software Environment > Running Tasks, look for bioiso.exe and ngciso.exe. If they are not running, the system may not meet the requirements for Enhanced Sign-in Security.
3. Re-enroll Biometric Authentication: Go to Settings > Sign-in Options, remove the existing facial recognition enrollment, and re-enroll your face.
4. Reinstall Camera Drivers: In Device Manager, expand the Cameras section, right-click on your camera device, and select Uninstall Device. Restart your computer, and Windows will attempt to reinstall the driver.
5. Restart Biometric Service: Remove any PIN from the system, then open a command prompt as administrator and enter net stop wbiosrvc && net start wbiosrvc. Check if the facial recognition feature works afterward.

If these steps do not resolve the issue, consider filing a feedback item using the Feedback Hub to report the problem.
