Do you know how windows terminates all the applications when user logs off? I did not think too much about this, and assumed that it is a normal process - after all the WM_QUERYENDSESSION and WM_ENDSESSION processing, the application main window closes, posts WM_QUIT and the application quits in a regular way.
But a recent bug reported for one of my GUI applications caused me to look deeper. The bug caused the application settings to be lost, and this made me look closer at what happens at logoff.
