You can use OpenInputDesktop MSDN

During logoff, the Input Desktop is inaccessible to the user, and the function retuns NULL.

ex: HDESK hDesk = OpenInputDesktop(0, FALSE, READ_CONTROL);

if (!hDesk) -- during logoff... -- else { --normal state-- CloseHandle(hDesk); }

In windows vista & 7, pressing CTRL+ALT+DELETE also brings to an inaccessible to the user desktop.

I believe the "correct" way is to listen to a WMI event.

Disclaimer: I have not tried this myself.

In console application, you can register a callback (SetConsoleCtrlHandler, CTRL_LOGOFF_EVENT).

In message-loop application, you can catch certain messages (WM_QUERYENDSESSION, WM_ENDSESSION).

See Logging Off (Windows) on MSDN.

WM_QUERYENDSESSION and WM_ENDSESSION are most likely what you're after.
