Solved windows update and hello disappeared

[3rdschulz]

hey guys,
I am on my 3rd day of my surface pro 4. I was using windows hello to sign in with facial recognition, it worked great. Today I updated windows and now hello is gone, its no longer even there and my camera is not recognized, it prompts to sign in with my pin code instead... worked fine the first 2 days but after the update it all went to hell. any ideas?

Do this reboot:
1) Hold power button for 30 seconds. Shuts down cold.
2) Hold volume rocker UP button and power on. Continue holding both for 30 seconds.
3) Exit the UEFI screen. Make no changes.

Good.
Marking solved. You needed to allow setup to also go through the boot processes, even after starting once since the update.
