Default Behavior
System Event Notification Service is a Win32 service. In Windows 8 it is starting automatically during the operating system startup. Then the System Event Notification Service runs as LocalSystem in a process of svchost.exe, sharing it with other services. If System Event Notification Service fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the SENS service hasn't been started.
Dependencies
System Event Notification Service can't start, if the COM+ Event System service is disabled or not available.
If System Event Notification Service is disabled, the COM+ System Application service will not be started and initialized.
