Default Behavior
System Event Notification Service is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the System Event Notification Service is running as LocalSystem in a shared process of svchost.exe along with other services. If System Event Notification 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 SENS service has failed to start due to the error.
Dependencies
System Event Notification Service cannot be started under any conditions, if the COM+ Event System service is disabled.
While System Event Notification Service is stopped, the COM+ System Application service cannot be launched.
