Default Behavior

Windows Biometric Service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Windows Biometric Service is started, it is running as LocalSystem in a shared process of svchost.exe along with other services. If Windows Biometric Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the WbioSrvc service has failed to start due to the error.

Dependencies

Windows Biometric Service cannot be started under any conditions, if the following services are disabled, deleted or working improperly:
