Disable Ctrl+Alt+Del Combination on windows7

Question

I\'m working on an app (Written in C#) that have a setting to run on KIOSK mode. I\'ve just an challenge here which is disabling Ctrl+Alt+Del

Answer 1

It is possible to block CTRL+ALT+DEL combination. However, you can't really disable it. As far as I know, there are two possible methods.

1. Remapping the keyboard layout. There is a registry binary key that allows you to remap keyboard layout:

HKLM\System\CurrentControlSet\Control\Keyboard Layout\Scancode Map

Please check this out: Disabling Windows Hot Keys

2. This method can be dangerous, but I haven't noticed any side effects this method can cause. The CTRL+ALT+DEL combination is handled by winlogon.exe. If your process has administrative privilege, you can suspend winlogon.exe. Hence, it cannot process the hotkey and nothing will happen if the user presses CTRL+ALT+DEL.
