Solution for PIN codes unavailable in Win10 System
Win10 PIN cannot be used. What should I do if Win10 PIN cannot be used for Logon? The PIN password is a newly added logon authentication method in Windows from Win8 and is strongly recommended by Microsoft. During the Win10 installation process, Microsoft will prompt that the user's traditional password is outdated. It is recommended to use a simpler but safer PIN code for logon.
If your device supports Windows Hello (iris scan or fingerprint scan), you also need to set a PIN code to log on to the device.
Some users may encounter PIN code unavailability during use. This is generally because the IPsec Policy Agent service is not enabled. In this case, you only need to set this service to automatic start, and manually enable it to restore the normal operation. The detailed operation process is as follows:
• Enter "service" in the search box of the taskbar and enable "service" in the search results ";
• Find the IPsec Policy Agent in the service and double-click it to open its properties.
• Set the Service Startup type to "automatic" and click "OK" to save the settings.
• Enable the service manually.
