Windows Defender Security Center Service is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the Windows Defender Security Center Service is running as LocalSystem in its own process of SecurityHealthService.exe. If Windows Defender Security Center 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 SecurityHealthService service has failed to start due to the error.
