title: Is there a Windows API for adding badges to taskbar icons?
body: <p>Spotify recently added a feature where the taskbar icon would have a red iOS-style badge with the number of songs in your inbox.</p>
  
  <p>The badge itself is definitely part of the icon, but I was wondering if the number might be added with an official API.</p>
  
  <p>If not, how might they be doing it? I've never had more than a few songs in my inbox, so maybe it just doesn't shows 1-9 and then 10+ or something, or could they be dynamically creating the image and setting it as the icon?</p>
  
  <p>I wasn't aware you could change the icon while the app is running.</p>
