The only fix? Deleting the driver’s biometric database from C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc and re-enrolling. For enterprise IT admins, this became a weekly ritual.
Importantly, these drivers do not store images of your face or finger. Instead, they create a mathematical representation (a hash) that stays encrypted on your device and never leaves for the cloud. How to Update or Reinstall Windows Hello Drivers windows hello driver
A 2024 analysis by a firmware security firm found that three popular laptop models shipped with Hello drivers that in certain power-save modes. Why? To save 50 milliseconds of boot time. The driver would skip checking the TPM’s signed nonce if the system resumed from sleep. That meant a malicious USB device could pretend to be a Hello camera and unlock the PC. The only fix

Microsoft patched it by enforcing on all Hello-compatible drivers—meaning the driver itself now runs in a virtualized secure environment, checked for signatures every few milliseconds.
Windows Hello drivers act as a bridge between the physical sensors on your device and the Windows Biometric Framework .
