Detecting windows shutdown event

Question

I have a windows Service always running once PC started, how would i detect using .NET 3.5 or WMI, when the user or some other application/process has requested a shutdown o

Answer 1

Use the Microsoft.Win32.SystemEvents.SessionEnding event.

However, note that you are in a Windows Service, and this event won't fire for you unless you create a hidden form in your service. You can get one of these for free by enabling the "Interact with Desktop" option on the service.

Answer 2

You're looking for the SystemEvents.SessionEnding event.

Occurs when the user is trying to log off or shut down the system.

Answer 3

Win32.SessionEnded event gets fired when the system is being shut down. You should attach to this in your program.
