title: How can a status bar be displayed on Windows 8 and Windows 10 desktop login screen programmatically?
body: <p>I am facing these problem:</p>
  <p>Our computers in our network perform a patch managment each day. These takes several minutes. Is it possible to show the status bar of these patching process on the login screen of all our computers? They are running on Windows 8 and 10. It would be cool, if that would be possible to do this in C# or C++.
  I only found post saying that maybe a GINA dll must be rewritten. Most post do say that that is not possible.</p>
  <p>I don't want the screen to be locked, so login should still be possible, while displaying the status bar.
  I do know that by changing a Reg. Key you can change the wallpaper, but that is not what I am looking for.</p>
  <p>Any help would be great.</p>
