I understand how frustrating this is, especially when Windows Hello works on a normal startup but not after a restart.
Based on your description and the steps you’ve already tried, this behavior is commonly caused by the biometric driver or device not properly reinitializing after a reboot, not a configuration issue.
What you can try next:
- Check camera power management
- Open Device Manager → expand Cameras
- Right-click your IR (Windows Hello) camera → Properties
- Go to Power Management tab
- Uncheck “Allow the computer to turn off this device to save power”
- Restart and test This is a common cause where the sensor doesn’t wake properly after restart.
- Reinstall the IR / Hello camera driver
- In Device Manager → Cameras
- Right-click your IR camera → Uninstall device
- If available, tick “Delete the driver”
- Restart the PC (Windows will reinstall it automatically)
- Test again Driver issues are one of the most frequent causes of Hello failing after reboot.
- Toggle Enhanced sign-in security (if available)
- Go to Settings → Accounts → Sign-in options
- Under Additional settings, look for “Enhanced sign-in security”
- Turn it OFF (temporary test)
- Restart and check Some hardware doesn’t fully support this feature, which can block biometric login after restart.
- Reset the biometric database
- Stop “Windows Biometric Service” in services.msc
- Go to: C:\Windows\System32\WinBioDatabase
- Delete contents of that folder
- Start the service again
- Re-enroll your face If the service briefly runs then stops, this can indicate corrupted biometric data.
If all of the above still fail, check whether the issue started after a recent Windows update, some updates have been known to affect Windows Hello behavior after restart.
Since this is a public forum, please note we don’t have access to your device or account, but these steps cover the most likely root causes for the scenario you described.
