Disabling the Ctrl+Alt+Del (and Alt+Tab) in all Windows Platforms

Hi There, I need vb code (preferably) that will disable the ctrl+alt+delete and alt+tab keys on ALL windows platforms. I manage to disable it on win9x platforms but not any of the NT platforms. So only those of you who have already disabled on NT platforms bid.
