Prevent Alt + CTRL + DEL

[ushtabalakh]

Is there anyway to not let the user see the task manager by pressing alt + ctrl + del? I want the operating system to ignore alt + ctrl + del and pretend it has not been pressed.

It's much easier to do this with Group Policy either on the machine or the server if you're using a network with a domain. You don't disable Ctrl+Alt+Del, but restrict the user's access to the Task Manager.

If you do decide to go with a coding solution, remember that the Task Manager can also be launched by right-clicking on the Task Bar and selecting "Task Manager..."

Sounds like maybe you are building a Kiosk or something. You can also use those policy settings to load a/your program in place of the desktop (explore.exe) which will take away the taskbar, desktop, etc.

HINT: Before you doing all of this however, make sure that you can set the policy settings from a second computer incase you lock yourself out of being able to access the policy settings on that pc. Been there, done that... not fun. LOL!

I do not have access to any of the methods you have mentioned, I'm looking for a vb.net solution not a windows solution.

One method that I was thinking about was to have a timer that sends "Esc" to the user every few milliseconds that way even if he presses ctrl + alt + del, he won't see anything because that windwos will close immediately.

The timer/ESC idea will kill resources and probably produce all kinds of other issues as well.

You are talking about catching/preventing a seriously high level API call. You can do some web searching and you might be able to find something. I did that and found a bunch of solutions but I really don't know any that work and have never tested any myself. I just know that the ctrl+alt+del combo is a high level code call.

I tend to agree with jebenson and SiriusBlackOp. This functionality would best be controlled by Windows. If that is not an option (maybe you are doing this on a home pc or such where there is not domain), my next bet would be to look for a third party program to do this for me. As Sirius said...you run the risk of locking yourself out of your own PC/causing some other Windows functionality you DO NEED not to work/etc.
