Most drivers manage physical things: a GPU, a network card, a touchpad. But a software driver for Windows Hello Face is different. It sits between the Windows Biometric Framework (WBF) and a compatible camera—usually an Intel RealSense, an OV20, or a custom near-infrared (NIR) sensor.
If this driver is missing, corrupted, or outdated, Windows Hello will fail to work, even if your camera hardware is fully functional.

The Windows Biometric Service (WbioSrvc) calls into the driver. The driver streams frames to a Microsoft-signed DLL— HelloFaceBiometrics.dll —which performs liveness detection, alignment, and feature extraction using hardware-accelerated instructions (AVX2 on modern CPUs).
When the driver is missing, outdated, or corrupted, Windows cannot access the IR camera, resulting in "Windows Hello couldn't turn on the camera" or similar errors. Common Symptoms of Driver Issues
