title: How to get Visual Studio 2013 manually into safe mode?
body: <p>I know this might a common question. I don't really know why but my VS 2013 got really really slow yesterday. Every open VS is sucking up 25% of the CPU-Power. When I start it in the Safe Mode, everything is allright. So it has to be thrid party extensions. </p>
  
  <ol>
  <li>I cann't figure out how to turn off all extensions. Via Tools/Extensions Updates I some extensions cannot be disabled or uninstalled (button disabled). Neither can I figure out what extension is malicious. </li>
  <li>Will it even help to reinstall the VS?</li>
  </ol>
  
  <p>thanks</p>
