Hello Sign-in Biometric driver re-install

[cisconice]

After a windows update, the hello sign-in was not working. I got error that said Couldn't turn on camera at the login.   When I look at the hello sign-in setting , it said windows couldn't find a compatible camera.   When I look at device driver, there was a big exclamation mark on the biometric driver for facial recognition.   Half asleep, I uninstalled it , thinking that after a reboot, it would re-install itself.    Well, I was so wrong.  It didn't.   Now I am on a hunting mission to find what I uninstall and try to install back.  I can't find anything in the hp download.  It could wrap up in some software package.   

If anyone know what is the driver, I would appreciate if you would share it with me.
