![]() In Linux, this keystroke combination is recognised by the keyboard device driver in the kernel. In both cases, the system flushes the cache, cleanly unmounts all disc volumes, but does not cleanly shut down any running programs (and thus does not save any unsaved documents, or the current arrangements of the objects on the Workplace Shell desktop or in any of its open folders). If it is pressed twice in succession OS/2 triggers an immediate soft reboot, without waiting for the session manager process. The normal session manager process in OS/2 versions 2.0 and later is the parent Workplace Shell process, which displays the "The system is rebooting" window and triggers a soft reboot. In OS/2, this keystroke combination is recognised by the OS/2 keyboard device driver, which notifies the session manager process. This allows the user to over-ride any "stuck" process, since no user-level program is able to define its own response to the Control-Alt-Delete key combination. As such, it is strongly reccomended that, following a process kill, you save your work in any other applications and restart the computer.Įntering the combination twice in succession will theoretically trigger a soft reboot, even if Windows has not yet been able to display the process listing (due to problems caused by other processes). Theoretically, the system's other processes should continue normally-in practice, using this key combination to terminate a program/process will result in "secondary damage" that may destabilize the system. Killing tasks/processes is useful, for instance, if a program has entered an infinite loop. ![]()
