Hi Michael,
This is Wil, one of the independent advisor, an expert with Windows 10 and a fellow Windows 10 user like you.
The password hint is only available if you are using a Local account to log in to Windows 10. It will appear on the login screen if you entered your password incorrectly. The password hint would only give you a hint that can help you remember your password.
I hope the information I provided will help you. If you need further assistance please do reply back and I will respond as quickly as possible. Have a nice day.
Thanks,
Wilfred P.
Independent Advisor
