I mean, this is basically why you press Ctrl-Alt-Del to log in on Windows NT and Win2k - because it's a keystroke that malware couldn't trap, so they can't put up a fake login screen because the OS will override it anyway.


There was no hardware or other low-level magic associated with C-A-Del.

Back in the NT days malware could totally intercept it, but it would have had to be in the kernel. Which was something of an improvement.

Thank you, DoD Orange Book.
