    My comment:
    This technique can not be used to block CTRL+ALT+DEL combination of keys.

    See also Microsoft Knowledge Base Article - 161133:
    HOWTO: Block CTRL+ALT+DEL and ALT+TAB in Windows 95 or Windows 98.

    I found a discussion on the Expert-Exchange, Interrupt Handler for 0x19 (Ctrl+Alt+Del) in VB6, that you may find interesting.

    Then an article written by Antσnio Feijγo, Lock Windows Desktop seems to answer many if not all questions and even offers some downloads.

    Read article Typename, Disabling Keys in Windows XP with TrapKeys by Paul DiLascia.
