There is a problem with the win8 fingerprint software installed

Hello. Provides you with a workaround for e7210001:

1: Check whether the "Windows Biometric Service" service item is closed, the service is turned off, and the settings can be set automatically.

<>2: If the above service still prompts "dependent service or group cannot start" when starting, you need to find its dependencies and set its dependent services to start automatically to start the service.

3: If the service starts normally and the fingerprint recognition still cannot be used, it is recommended that you reinstall the fingerprint driver of the computer.

In the end, I guess it may be that the computer optimization software I installed turned off this service in order to optimize my computer, so the fingerprint software could not be started;

If you have used 360 software optimization, you can start 360 Security Guard--Optimization Acceleration--Startup Item--Application Software Service--ThinkVantage Communication Tool Service.

Microsoft's default built-in administrator account cannot be logged in with a fingerprint. Create a new administrator account to log in with your fingerprint.
