And it worked. I now have fingerprint scanning to sign on. What is weird is that "Windows Hello" still does NOT show in the settings sign on options. So I use HP Client Security app (part of HP ProtectTools Security Manager) to load and manage fingerprints.
I totally agree - it's very annoying that HP hasn't yet released updated drivers for the fingerprint scanner (VFS291) that are compatible with Windows Hello.
This worked perfectly using both posts starting with xbalanke and then Josh5.
