For a program I am working on, I need to disable CTRL-ALT-DEL, and the Windows keys (in fact the entire start menu). I know this can be done by fooling windows into thinking a screensaver is active, but this also has the side effect of disabling ALT-TAB.

Is there another way to disable the CTRL-ALT-DEL, Windows-key combinations, etc, without affecting the ALT-TAB combination?

Thanks

Colin
