title: How to unInstall older versions of visual studio safely
body: <p>I kept on installing Visual Studio versions as they were released.
  2010 and 2012 &amp; 2013. Now I want to cleanup my system from older versions i.e. ( VS-2010 &amp; VS-2012) &amp; keep the latest one only!</p>
  
  <pre><code>How can I uninstall older versions safely without a need to re-install VS-2013.
  </code></pre>
  
  <p>P.S. I am afraid that if I un-install older versions that would delete some shared system files away which would be needed for VS-2013 to work properly.</p>
