Sorry for the spelling mistake. I mean "disabling" instead of "diabling" in the title.

Use the Ctrl2Cap sample (by Mark Russinovich). (for Win95) (for WinNT)

The example that you have said is a VxD. It has been developed using DDK. I want to use only windows API and MFC. If i am not clear please let me know. There is an undocumented API "SystemParametes" which enables or disables "alt+tab" and "ctrl+alt+delete", but I don't know how to use it. I am looking for something similar or easier way to do it.

There is no way to do that by the API functions.
