Hi,

There's a Closing event on the Form class, as well as a Closed event, as far
as I remember. System shutdown can also be handled by tapping into the
WndProc and handling the appropriate Windows notification
(WM_QUERYENDSESSION if my memory serves me well).

I think the Microsoft.Win32 has some managed wrappers for the Session
ending.
