Thank you Robin_Ben and thanks DCHarrison. This has been a thing since cumulative updates on my Samsung 2-1 Galaxy book pro. I followed what Robin_Ben said:
"Just right click on the said device> properties> driver and then disable the device and then again enabled it. YOUR PROBLEM IS RESOLVED!!! The exclamation sign will disappear and you will also find fingerprint options in sign in options."
Worked like a charm. much easier than searching driver and system updates. I appreciate the help
