Hello, thank you for reaching out to Microsoft Q&A.
Delete the contents of the NGC folder, then set up your PIN again.
- Go to C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\NGC
- Delete all the contents of the NGC Folder.
- Restart your PC.
Then go to Start > Settings > Accounts > Sign-in options > Windows Hello PIN > Create a new PIN.
(Make sure you take permissions before deleting the contents of the NGC folder in the security settings for that folder. (OR) You can boot your PC in safe mode and then delete the contents of that folder.)

If you are unable to access that folder and delete the contents, here's what you can try:
- Open Command Prompt as Administrator.
- Run these commands one by one and click Enter for each command.
takeown /f "C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc" /r /d y
icacls "C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc" /grant Administrators:F /t
rd /s /q "C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc"
Once finished, restart your Computer and set up your PIN again.
