Disable Ctrl-Alt-Delete

[booeyOH]

Hello,
I have someone writing a program for me, a Kiosk type program, and we are stuck. If the user welcome screen is disabled, there is no way to keep a user from pressing ctrl-alt-delete and getting the task manager window.

Help!

Any ideas would be welcomed.

Thanks,
Bryan

This code only works in Windows 9X, we are using mostly XP systems

Any other ideas?

You can try here:

You could also try an external program, such as:

The msgina.dll only takes effect on restart, and I would prefer not to have the user have to do this. Also we can't find a way to disable the "Shut Down" in the ctrl+alt+delete window.

And the program in the link also requires a restart

All ideas still welcome (And thank you VRoscioli!)

If I'm not mistaken, Ctrl-Alt-Del has significant security protection in NT (including XP). Therefore you'll probably be very hard-pressed to find something that won't require a restart to take effect. Did you try the registry solution available in the first link in my previous post?

Yeah, I guess it requires a restart. And if I understand it correctly, it would need a restart everytime you wanted to run the program, so you would start the computer, run the program, it would set the value, you would need to restart, then if you wanted the computer to be "normal", you would need to reset the value and the restart again. Seems like there would be an easier way.

Thanks,

A keyword search in this forum on this subject will provide the core answer:

1) you cannot disable CAD
2) you can change the fundamental operation of CAD, but this requires you to write a GINA replacement. And you can't really do that in VB


However, your goal is to prevent the task manager from coming up, and you can do this under Windows 2000, XP, W2K3 (and, presumably, Vista) with a local group policy (the registry setting that VRoscioli mentions is the manual way of doing this, but I'd recommend doing it the formal way:

Start/Run/gpedit.msc

In the Group Policy settings window
Select User Configuration
Select Administrative Templates
Select System
Select Ctrl+Alt+Delete options
Double-click the Remove Task Manager option
Select Enabled

All done. Now CAD just brings up a dialog saying that Task Manager is disabled, with an OK button.
