Programmatically disabling Taskmanager using c#

问题

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?

回答1:

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());
    }
}

Just set the appropriate registry key:

public void SetRegistryKey(Microsoft.Win32.RegistryKey regHive, string regKey, string regName, string regValue)
{
    bool response = false;

    Microsoft.Win32.RegistryKey key = regHive.OpenSubKey(regKey);
    if (key == null)
    {
        regHive.CreateSubKey(regKey, Microsoft.Win32.RegistryKeyPermissionCheck.ReadWriteSubTree);
    }
    key = regHive.OpenSubKey(regKey,true);
    key.SetValue(regName, (string)regValue);
}

SetRegistryKey(RegistryHive.CurrentUser, "Software\Microsoft\Windows\CurrentVersion\Policies\System", "DisableTaskMgr", 1)
