title: Disable Task Manager using c# from Limited User Account
body: <p>I need to disable and enable the taskmanager from my application.
  I am doing this for my Kiosk application. I know i can do this
  by changing the Key in registry using below code. But the problem
  is my kiosk application will run in limited user account which does
  not allow the application to change key in registry level.</p>
  
  <p>Code working perfectly in Administrator account :          </p>
  
  <pre><code>    RegistryKey regkey;
          string keyValueInt = "1";
          string subKey = "Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System";
          regkey = Registry.CurrentUser.CreateSubKey(subKey);
          regkey.SetValue("DisableTaskMgr", keyValueInt);
          regkey.Close();
  </code></pre>
  
  <p>How can i achieve this in Limited user account ?</p>
