Hello,
Welcome to the Microsoft Windows Community.
Good afternoon. To provide a more accurate solution, please share a screenshot of your system information; simply press Win + R, type msinfo32, and press Enter. Then, do the following:
1. After logging in, press Win + I -> Accounts -> Sign-in options.
2. Click on PIN -> then click Remove and restart your computer.
3. You will need to enter your password to log in; then, return to the Accounts panel -> PIN -> Create PIN.
This should work.
