So basically, I have used fingerprint to log into my Microsoft account on my laptop until today. I have disassembled my laptop today but everything else works fine. When I go to settings there is no option to enable Windows Hello like before (I don't have 3D camera but fingerprint was working). I think there were no drivers for it so I don't know what went wrong. Drivers are updated, also checked with HP Support Assistant. Also, I downloaded Validity Fingerprint Sensor Driver for Windows 8.1 and nothing changed.
