title: Get a list of apps (or windows) currently visible in the windows task bar
body: <p>I need to find a list of items that are currently displayed in the Windows task bar.</p>
  
  <p>I know how to get a list of active processes or top-level windows but that won't do.
  Some appear in the task bar, some don't.
  It is possible for an app to have the top level window and still not appear in the task bar.</p>
  
  <p>I have tried to enumerate through all child windows of the task bar but that didn't get me very far either.</p>
  
  <p>I don't mind if I get a list of window (or icon) handles or a list of processes.</p>
