Sergey is totally right. You still have two options to display some information on logon screen:
1) Use registry to add logon message. See: http://www.techrepublic.com/blog/window-on-windows/adding-messages-to-windows-7s-logon-screen/4390[^]
2) Use logon wallpaper: http://www.techrepublic.com/blog/window-on-windows/change-and-customize-windows-7s-logon-screen-wallpaper/2135[^]
 
[Update]
I found a really interesting thing for you: http://logonscreenlauncher.codeplex.com/[^]

Good suggestion, my 5.
OP really needs to tell us the ultimate goals.

Thanks for all your efforts. But what I am trying is that whenever my application in User Mode received any mesaage and screen is locked then I want to show some notification on cntrl+alt+del screen.

I don't think you can intercept this keyboard input at the level of any user-mode code. I don't know if it can be done in Ring 0 code, but it means the level of the kernel-mode driver or something like that.
 
This key combination is hidden by the OS from the user-code processes, for apparent safety reasons. If some code blocks Ctrl+Alt+Del, only a reset or power button can help, but its operation can also be blocked in system settings. What else to do then? Only removing the power… Smile | :)
