When I quit work for last employer, I took the laptop with me (Lenovo T420).
When I disabled the domain, the username I was using before disappeared (tied to domain).
I already had local admin user created, and all the data backed up so that was not a problem.
But the problem is that previous domain user had a Windows Hello fingerprint associated with it. And although I went to the bios and deleted all fingerprint data, and also installed Lenovo ThinkVantage Fingerprint software and deleted all fingerprints in it as well, Windows 10 still does not let me associate index finger with my new local account, saying:
That fingerprint has already been set up on another account. Try a different finger.
I removed the complete c:\users\olddomainuser folder, and used the Control Panel to remove olddomainuser – but error still persists.
Where does Windows 10 store the Windows Hello/biometric data – can i reset/delete it, and start fresh without reinstalling Windows?

I have a similar problem which still persists after resetting TPM and reinstalling the OS completely...
However, some people have reported success after deleting the file inside
and rebooting. So you might give that a try. Note that you will have to disable the Windows Biometric Service to delete the file.
