If your Windows Hello fingerprint function is showing as 'unavailable', it could be due to several reasons related to hardware compatibility or settings. Here are some steps you can take to troubleshoot the issue:
- Check Biometric Device Compatibility: Ensure that your fingerprint sensor is compatible with Windows Hello. You can check this by going to Device Manager and expanding the Biometric devices section. If the device is not listed or has a warning icon, it may not be compatible.
- Driver Issues: If the fingerprint sensor is present, try reinstalling the driver. Right-click on the fingerprint device in Device Manager and select Uninstall Device. After uninstalling, restart your device; Windows should attempt to reinstall the driver automatically.
- Windows Hello Settings: Go to Settings > Accounts > Sign-in options and ensure that Windows Hello is set up correctly. If the fingerprint option is still unavailable, try removing any existing PIN and re-adding it.
- Virtualization Based Security (VBS): Make sure that VBS is running. Open System Information and check if Virtualization Based Security is listed as Running. If it is not, you may need to enable it in your system's BIOS settings.
- Biometric Service: Restart the biometric service by opening a command prompt as an administrator and entering
net stop wbiosrvc && net start wbiosrvc.
If you have checked all these aspects and the fingerprint option remains unavailable, it may indicate that your device does not meet the requirements for Enhanced Sign-in Security (ESS) or that there is a hardware issue.
