title: How can an application display an object on the Windows taskbar?
body: <p>There are several applications around that display objects on the Windows taskbar but do no implement the IDeskBand interface.  For example, the Lenovo batter meter and <a href="http://www.batteryinfo.de.vu/" rel="nofollow noreferrer">Notebook BatteryInfo</a>.</p>
  
  <p>For example:</p>
  
  <p><a href="http://home.arcor.de/batteryinfogateway/img/taskbar_new.png" rel="nofollow noreferrer">Notebook BatteryInfo http://home.arcor.de/batteryinfogateway/img/taskbar_new.png</a></p>
  
  <p>In the picture above, the object on the taskbar is put there by the application and disappears when the application closes.  This is different than IDeskBand in which the COM object is loaded directly by explorer.exe.</p>
  
  <p>What API/Method can be used in Windows to accomplish that?</p>
