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.

Restore Default Startup Configuration for System Event Notification Service

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_SENS_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

The SENS service is using the sens.dll file that is located in the %WinDir%\System32 folder. If the file is corrupted or deleted, you can put it back in there.
