Re: how can I disable ctrl+alt + del, and windows key in vista.

you have to maintain your own state machine b/c you will only see one key
up/down at a time in a KEYBOARD_INPUT_DATA. What SystemBuffer are you
talking about? in the read irp? are you filtering above kbdclass or below
it?

Ok I've gotten as far as writting and installing a driver. I can disable
Ctrl-Alt-Del by always changing the Ctrl key, what I can't work out how to
do
is trap Ctrl-Alt-Del explicity.

What scan code/codes do I need to use? I tried changing the Ctrl key to
something else when Alt (0x38) and Del (0x53) is also pressed but it
doesn't
work.

How can I detect the key combination from SystemBuffer?

You can trap the windows key using a keybroad hook with the
SetWindowsHookEx
api. Just eat the event.

I'm also interested in how to trap ctrl-alt-del on vista, and have been
looking at the DDK with the hope of writting the filter driver, but
know
very
little about this.

Did you have any luck? Has anyone got any pointers, sample code?
