Notebook Operating System and Recovery

I finally got Windows 10 installed via the update method from Windows 7 Pro 64 bit.  But now I am unable to get the fingerprint scanner to work. It shows up in Device Manager as working okay and drivers installed. However in Win10 Settings, Logins, the option to enable the fingerprint scanner does not appear.  Now what?

One of the prerequisites to enable the fingerprint scanner in Win10 is to first set up a PIN login, which I did. After that and rebooted  I was offered the PIN signin, which worked.  But STILL, nothing I could do would let me setup the fingerprint scanner in Windows login settings. It's as though there was no fingerprint scanner installed on the machine.

I checked the HP Support website for an updated fingerprint scanner driver, but none was offered. I tried uninstalling the hardware in Device Manager. It appears under Biometric>Validity Sensor.  After uninstalling I made it search for new hardware. It found that sensor and reinstalled the drivers. It said the device was working. 

But after reboot I am still unable to see an Enable Fingerprint Scanner choice in Windows 10 Settings>Accounts>Sign-in Options. The items in the right column in that section are Require Sign-In; Password; PIN; Picture Password; and Related settings.

When I search Win 10 settings for Fingerprint Scanner, it provides a link that takes me to that Sign-In Options page, but there is no item for Hello or Setup Fingerprint Sign-in.

Has anyone been able to get fingerprint scanner to work in Win 10 with an HP ProBook laptop?
