hii....I am developing a window application how is it possible to disable special keys like control+alt+del to perform while running the application, i used keyhook method to disable almost all keys like windows,alt+f4 etc....

A: 

Ctrl+Alt+Del is "special" for a reason.

What kind of software are you writing?

Not least, you are forcing me to use a mouse...

Edit

Even if you did write a new GINA DLL, I'd be surprised if you could install it. You won't be able to on a Windows x64 OS without running in test mode etc. Which I would not allow you to do.

So, what kind of software requires you to damage my OS installation?

A: 

You cannot disable Ctrl+Alt+Del, it's pretty low level and would be considered a security risk otherwise. Is there any particular reason you want to disable it?

If you're writing a Kiosk-style application, you will need to write a new GINA DLL that traps the Ctrl-Alt-Del sequence and ignores it. Or just use a keyboard that doesn't have a Ctrl, Alt, or Del key...
