title: Command line to start visual studio and disable add ins/Extensions for that instance
body: <p>I am writing a Visual Studio template wizard.  And to debug it I have it start a new instance of Visual Studio 2010.</p>
  
  <p>My Visual Studio 2010 takes a good while to start up.  I believe that this is due the the add-ins and extensions that I have installed for visual studio.</p>
  
  <p>I would rather not go disable them all (I really like them).  So I was hoping there was a way to disable them via the command line.  </p>
  
  <p>Just run a clean Visual Studio instance.</p>
  
  <p>Is there a way to do that?</p>
