NetBIOS Interface is a file system driver. In Windows 10 it is starting at Kernel initialization. If NetBIOS Interface fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the NetBIOS service has failed to start due to the error.
