Hi FF. I'm Greg, an Independent Advisor.
I can help you reset the PIN to get it working or turn off the nag message:
Reset See here how to reset the PIN in Windows 10 when it will not work from Settings > Accounts > Sign In Options:
Open Windows File Explorer using the file folder icon on your task bar.
Tick the box in File Explorer View tab to Show Hidden Files.
Browse to C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc
Delete or rename to Ngc.old this folder to reset the PIN.
**You may need to first take ownership of the folder: https://www.tenforums.com/tutorials/3841-add-ta...
Once you delete or rename the folder it will recreate it so you can add a PIN normally in Windows Settings > Accounts > Sign-In Options. You may need to restart the PC first.
For any unexpected problems see the full illustrated tutorial covering all possible problems here:
