Hi Rana Zeen Shan,
Thanks for reaching out to Microsoft Q&A Forum. I understand that Windows Hello Face has stopped working on your Windows 11 Home device for a long time, even though it previously worked and basic checks appear fine.
Please make sure you already tried the Q&A Assist steps. In addition, please try the following.
To better understand the scope, I’d like to clarify a couple of points first:
1, What is the exact device model you are using, and does the camera work normally in apps like Camera or Teams?
2, In Sign-in options, do you see any specific error message for Windows Hello Face, or is the option present but not functional?
In the meantime, you can try these steps:
Disclaimer: The steps below may result in permanent data loss. Please ensure important data is backed up before proceeding.
1, Check camera privacy permissions
- Open Settings, select Privacy & security, then select Camera
- Make sure Camera access and Let apps access your camera are turned on
- Confirm that Windows Hello Face is not blocked from using the camera
2, Verify Windows Biometric Service status
- Press Windows key + R, type
services.msc, and press Enter - Locate Windows Biometric Service
- Ensure Startup type is set to Automatic and the service status is Running
- If it is running, select Restart
3, Reset Windows Hello local enrollment data
- Sign in using a password instead of Windows Hello
- Open File Explorer and navigate to
C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft - Take ownership of the
Ngcfolder, then rename it toNgc.old - Restart the device and try setting up Windows Hello Face again
4, Check for firmware-level camera disablement
- Restart the device and enter BIOS or UEFI settings
- Look for any option related to IR camera, Hello camera, or privacy camera control
- Ensure the camera is enabled, then save changes and restart
5, Create a new local test account
- Open Settings, select Accounts, then select Other users
- Create a new local account and sign in to it
- Check whether Windows Hello Face works in the new account
