title: Removing a pinned app's icon from the Windows 7 taskbar on the application's major upgrade with WiX
body: <p>After removing a WPF application which were installed with WiX, the app's icon, previously pinned to the Windows 7 taskbar, have not been removed automatically. It remains orphaned and needs to be removed manually. Is it a supposed, typical behaviour?<br>
  The problem is that after a major upgrade of the application, the pinned icon remains inactive and needs to be manually deleted and repinned. It confuses some users.</p>
  
  <p>Is there a possibility to delete or reactivate the app's icon, pinned to the Windows 7 taskbar, when doing an application major upgrade with WiX installer?</p>
