Set PIN as default sign-in option

Hi,

On the login screen below the password box click on Sign-in Options. You can view two option, one for password and one for Pin. Click on PIN and enter the pin. When you restart the computer, by default Windows will remember the previous option which you have chosen to login to Windows (PIN).

Sign in to or out of Windows

Hi,

Sorry, to know that you are facing this issue.

• Did you follow all the troubleshooting steps suggested in this thread?

If you have tried all the steps, I would suggest you to run the System File Checker tool (SFC.exe) scan, to fix missing or corrupted system files. Windows Store might crash if system files are corrupted.
