Press Windows key + I to open Settings.
Click Accounts and select Sign-In options.
Locate Fingerprint or Facial Recognition options and click Remove under them.
After that, click Get Started and follow the on-screen instructions to reset Fingerprint and Facial Recognition.
Reboot your PC if needed.
2. Modify Group Policy Settings (for Pro version only)
Creators Update might have modified some of the crucial settings of Group Policy. Therefore, we would recommend to launch the Group Policy Editor and check/edit the settings related to Windows Hello functionality.
Pres Windows key, type gpedit, and press Enter.
Click on Computer Configuration and open Administrative Templates.
Select Windows Components and open Biometrics.
Click on Facial Features and right-click on Configure enhanced anti-spoofing option.
Select Edit and disable the Configure enhanced anti-spoofing feature.
Reboot your PC.
3. Update drivers
If some of the system drivers, most probably webcam and fingerprint reader drivers, were corrupted during the upgrade process, Windows Hello may fail to perform. To fix that, try to update the corresponding drivers:
Right-click on Windows key and select Device Manager.
Locate the Hello, webcam, and fingerprint drivers individually and right-click on each of them.
Select Remove driver software and wait for the removal to be finished.
Repeat the removal with all Windows Hello related drivers and then reboot your PC.
Once done, open Device Manager, click Action -> Scan for hardware changes.
The system should automatically detect and reinstall the drivers.
If none of the methods listed above helped to fix Windows Hello problems, you can roll back Fall Creators Version 1709 in Settings>Update & Security>Recovery and then hide it until it matures using the Hide Updates Tool downloaded from here: http://download.microsoft.com/download/f/2/2/f2...
I If that doesn't help then I'd run a Repair Install by installing Media Creation Tool to choose Upgrade Now. This reinstalls Windows while keeping your files, programs and most settings in place. It also advances you to the newest version which you need anyway, and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m...
