I need to make my application "unclosable", ie. I don't want users to be able to close it. This is fairly easy to to in Windows9x, just disable ctrl-alt-del and you're set.
However, I need this to work under Windows 2000. I think it's impossible to disable ctrl-alt-del in Win2k right? Please correct me if I'm wrong, and maybe give a solution to it :=)
But is there a way to hide my program from the process list, so even if the user presses ctrl-alt-delete, he will not be able to select my program and kill it?
Another thing I've seen, it seems to be impossible to kill some processes like LSASS.EXE for example, all you get is an "access denied error". Is it possible to protect my program with something like that?
All input appreciated!
P.S I'd prefer code, not components, using components is the last resort in this case.
