title: How to change Windows cursor in WPF?
body: <p>I like to change the cursor, when user clicks a button. I can use FrameworkElement.Cursor. But it only changes the cursor for my current App. </p>
  
  <p>But I need my entire Windows cursor should change. I mean if you move the mouse outside the my app, it should show my cursor (not the default arrow).</p>
  
  <p>How to achieve this?</p>
