title: Custom search tab in Windows start menu search with C#
body: <p>I am interested to know how can I do the same thing that the apllication listed below does:
  <a href="http://robotification.com/start-menu-calculator/">Start Menu Calculator</a></p>
  
  <p>I want to know how can I create an custom tab in Start Menu Search and then handle it with my WPF application.  It should only be enabled until my application is running.( Just like what <a href="http://robotification.com/start-menu-calculator/">The calculator does</a> )</p>
  
  <p>I read something about <a href="http://archive.msdn.microsoft.com/WindowsAPICodePack/"><strong>windows API Code Pack</strong></a> and I downloaded it but I don't know how can I use it.  I searched through it but I didn't find anything.( If you know how I could do this using with Windows API Code Pack, please write an example that explains how to do it in C#)</p>
