Windows Hello PIN/Fingerprint “This option is currently unavailable”

I found the solution. The reason is that Windows Hello is managed differently on domain joined computers, starting with the anniversary update. To get it to work you have to follow these steps:

1) Setup a Group Policy Central Store (you should already have that)

2) Get Windows 10 Anniversary Update Group Policy Templates. You can do so by copying your files from PolicyDefinitions (in windir on a Win10 Anniversary Update machine) into the PolicyDefinitions of the central store. You might copy those files first to a file share, because of permissions your regular user should not have on the central store.

3) Setup a new GPO or add to an existing the following settings to enable Windows Hello:

• Computer Configuration/Policies/Administrative Templates

.../Windows Components/Windows Hello For Business/ Use biometrics => Enabled

.../Windows Components/Windows Hello for Business/ Use a hardware security device => Enabled (if you want to use TPM instead of key or certificate based activation for Windows Hello). Note that in general all business computers should have TPM

.../System/Logon/ Turn on convenience PIN sign-in => Enabled (This is the key. This enables PIN sign-in which in turn will enable Hello, together with the other settings.)

.../Windows Components/Biometrics/ Allow domain users to log on using biometrics => Enabled (I think this is enabled by default, but being explicit makes GP management a lot easier.)

You will find more optional configuration possibilities in System/Logon and Windows Components/Biometrics and Windows Components/Windows Hello for Business.

Most important excerpt:

Beginning in version 1607, Windows Hello as a convenience PIN is disabled by default on all domain-joined computers. To enable a convenience PIN for Windows 10, version 1607, enable the Group Policy setting Turn on convenience PIN sign-in. Use Windows Hello for Business policy settings to manage PINs for Windows Hello for Business.

If you want to use key or certificate based Windows Hello you can follow the guides in the links. Don't get confused though. You can still use regular TPM for normal Windows Hello.

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

C:\\Windows\System32\WinBioDatabase\

and rebooting. So you might give that a try. Note that you will have to disable the Windows Biometric Service to delete the file.
