MORE INFORMATION

A program that runs as a service can call RegisterServiceCtrlHandler to register a service control handler function for handling its service control requests, and can register a console control handler using SetConsoleCtrlHandler for receiving control events. If the computer is shut down programmatically by using ExitWindowsEx or InitiateSystemShutdown, the service control handler should receive a SERVICE_CONTROL_SHUTDOWN notification and the console control handler should receive a CTRL_LOGOFF_EVENT notification followed by a CTRL_SHUTDOWN_EVENT notification.

If the computer is shut down manually by the user at the console or programmatically when a user is logged on to the computer locally, the service control handler receives a SERVICE_CONTROL_SHUTDOWN notification and the console control handler receives a CTRL_LOGOFF_EVENT notification followed by a CTRL_SHUTDOWN_EVENT notification as expected.
