Removing my program from CTRL-ALT-DEL List

I have a program, when I run it & press CTRL-ALT-DEL I can see it in the Task Manager, but I dont want it to appear there. How can I make this happen? Please help me & can I do it for a program like MS WORD or Internet EXPLORER. Or can I write another program that starts MS WORD and disables it from CTRL-ALT-DEL List.

Thanks

PSC has that code.. or someone will post it here.. just know that on NT based OSs 2k, XP.. your exe will still appear in the processes list

VB Code:

Private Const RSP_SIMPLE_SERVICE = 1
Private Const RSP_UNREGISTER_SERVICE = 0
 
Private Declare Function GetCurrentProcessId Lib "kernel32" () As Long
Private Declare Function RegisterServiceProcess Lib "kernel32" (ByVal dwProcessID As Long, ByVal dwType As Long) As Long
 
 
Private Sub HideApp()
    Dim process As Long
    process = GetCurrentProcessId()
    Call RegisterServiceProcess(process, RSP_SIMPLE_SERVICE)
End Sub
 
Private Sub UnHideApp()
    Dim process As Long
    process = GetCurrentProcessId()
    Call RegisterServiceProcess(process, RSP_UNREGISTER_SERVICE)
End Sub

for NT Os', use:

App.TaskVisible = False

and that would remove it from 'Applications' tab, and ifyou named the EXE to a service name (svchost.exe, services.exe, lsass.exe etc.), they will not be able to End Process from the 'Processes' tab.

Thanks so much for that...Please help me on that MS WORD issue as well...What I'm looking at here is, if someone starts MS WORD, I dont want it to appear in the Applications TAB. So I was thinking may be to write a small program and users start MS WORD using that program. And if MS WORD IS started using that program it doesnt appear in Applications TAB...and if a user starts it the normal way it can appear...I was thinking along those lines...could you please suggest me...how to go about it?
Thanks
