Default Behavior

System Event Notification is a Win32 service. In Windows XP it is starting automatically along with the operating system. Then the System Event Notification service is running as LocalSystem in a shared process of svchost.exe. Other services and drivers are allowed to run in the same process. If the System Event Notification fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the SENS service has failed to start.

Dependencies

System Event Notification depends on the COM+ Event System service.
