The are multiple ways to unlock your Windows 10 computer.
I personally prefer the fingerprint option because its faster and more convenient.
your rig will then create a special folder to store your login information.
Windows 10 stores all the information related to your PIN tweaks in the Ngc folder.
The folder is located at the following location: C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft.
In this manner, youll remove all the data about your current PIN controls.
If you cant add a new PIN, you should probably first take ownership of the Ngc folder.
To do that, launch Command Prompt as an admin and enter the commands listed below.
Hit Enter after each command.
Try logging in again or set up a new PIN code.
look to see if this solution solved your problem.
