Method for XP or earlier is slightly different from Vista/Win7 from my experience. For XP or earlier, return 0 for WM_QUERYENDSESSION and this should be enough. For Vista/Win7, I haven't found a way to entirely stop logging off. But temporarily blocking logging off is possible. I would return 1 for WM_QUERYENDSESSION and register a blocking reason during WM_ENDSESSION, by calling ShutdownBlockReasonCreate. Then call ShutdownBlockReasonDestroy when your application is finished running. You should obey the description mentioned in WM_ENDSESSION Message[^] and WM_QUERYENDSESSION[^] to make sure both user and Windows system are happy.

He he, no but the PC is running an important control system that the normal user is not authorised to shut down. However, if the user logs off, it closes my application.
