Hi Ricardo,
I added the key "HKEY_LOCAL_MACHINE" and then click on the plus sign and selecting the options such as "SOFTWARE" and then "Policies" and following, at the end it is necessary to add the DWORD that I indicated.
Nothing changed, the "This option is not available" to add a finger or change pin etc.
Any other suggestion? this is a common problem to all Windows 10/11 users, must have affected millions of users.
