in reply to Windows Signals"

When a logoff event occurs, the system notifies all processes in the system as follows:

All windows of processes in the logon session being logged off receive the WM_QUERYENDSESSION (0x0011) and WM_ENDSESSION (0x0016) messages. All windows on the desktops of the window station being logged off receive these messages, even if the windows belong to processes running in another logon session.

    For simple console apps, you can also call SetConsoleCtrlHandler() and the message sent for logoff is CTRL_LOGOFF_EVENT
