| Symptom | Likely cause | Fix |

| Driver missing in Device Manager | Windows update removed it, or OEM didn’t install | Reinstall from Settings → Windows Update → Optional updates |
| Yellow exclamation mark | Corrupt or wrong driver version | Right-click → Update driver → Search automatically |
| “We couldn’t find a compatible camera” | IR camera disabled or driver not loaded | Check Camera privacy settings (Settings → Privacy & security → Camera) |
| Driver present but face setup fails | Windows Biometric service stopped | Run services.msc → Windows Biometric Service → Start + Automatic |
2. "We couldn't find a compatible camera"
This is a driver signature issue. The Windows Hello Face Software Driver has been disabled because of a driver integrity failure or a conflicting third-party camera application (like Discord or Zoom) that held exclusive control of the IR sensor.
