title: Updated Ionic CLI but shows previous version (Windows)
body: <p>I want to update the Ionic CLI tool to the latest version (v1.3.13).
  I do this:</p>
  
  <pre><code>npm update -g ionic
  </code></pre>
  
  <p>It appears to work.  No errors, it gets all the files successfully.</p>
  
  <p>But - I do this:</p>
  
  <pre><code>ionic --version
  </code></pre>
  
  <p>And it shows the previous version!  Why?</p>
