If a user fires up Task Manager and clicks \u201cEnd Task\u201d on your program, Windows first tries to shut down your program nicely, by sending WM_CLOSE messages to GUI programs and CTRL_CLOSE_EVENT events to console programs. But you don\u2019t get a chance to intercept TerminateProcess. Why not?<\/p>\n

TerminateProcess<\/a>\u00a0is the low-level process killing function. It bypasses DLL_PROCESS_DETACH and anything else in the process. Once you kill with TerminateProcess, no more user-mode code will run in that process. It\u2019s gone.\u00a0Do not pass go. Do not collect $200<\/a>.<\/p>\n

If you could intercept TerminateProcess, then you would be escalating\u00a0the arms race between programs and users<\/a>. Suppose you could intercept it. Well, then if you wanted to make your program unkillable, you would just hang in your TerminateProcess handler!<\/p>\n
