Programatically disabling Taskmanager using c#

I am working on a Kiosk application, I need to disable the taskmanager. So that when the user press [Ctrl + Alt + Del] and [Ctrl + Shift + Escape], the taskmanager should not pop up. How?

Answer

You can do it by changing the group policy settings.

public void KillCtrlAltDelete()
{
    RegistryKey regkey;
    string keyValueInt = "1";
    string subKey = "Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System";

    try
    {
        regkey = Registry.CurrentUser.CreateSubKey(subKey);
        regkey.SetValue("DisableTaskMgr", keyValueInt);
        regkey.Close();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}
