Thank you very much for the reply! Much appreciated. I agree that the camera failure could be coincidental with the upgrade push from Norton. I have since (moments ago) resolved the issue.
- 1 - I tried a restart - no resolution.
- 2 - I tried to use the built-in Microsoft diagnostic functions in the device manager, without a restart and followed by a restart - no resolution.
- 3 - I uninstalled the camera via the device manager and restarted - no resolution.
- 4 - Via device manager, system devices, I updated each the drivers for each of: Microsoft camera, front camera, and back camera. Each time it said that I had the current driver. Then I did a shutdown (not a restart) followed in 30 seconds by a start. This time the Windows Hello function with the camera face recognition worked. Problem resolved.
Thanks again.
