When you go to Start -> Turn off or whatever, what code does it execute at that point? Does it use ExitWindows(Ex)?
I'm curious because I want to prevent shutting down the computer using that button. I want it to be shutdown by physically pressing the button on the computer case. So if you have any methods other than hooking ExitWindows that would be appreciated as well. Thanks

Why would you honestly want to do that?

Oh, there's a windows setting somewhere where you set the behavior for hitting the power button in windows.

edit: power saving settings. You can set the power button to do nothing.

I think he means to only shut it off when the power button is pressed and blocking the start->shutdown way

Not sure if that's possible, but perhaps there's a windows policy you can set for that
Or perhaps you could enumerate all the windows in the start menu, find the shutdown item and hide it's window (hidewindow)

You need to have access to the registry.

Press Start > run

then type "regedit" this opens registry editor, locate these directories:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer

check if there is a dword value called "NoClose" if there isn't create it. Set it to 1 to prevent shutdown.

if you dont call ShutdownBlockReasonDestroy, and you close the window, can you shutdown?

I don't know why you want to make yourself more problems than you have to, just use register and it will prevent shutting down through start > shutdown. Windows sends messages to all programs and then they terminate don't remember message ids at the moment. If programs don't terminate themselves, windows kills them.
