title: update git via cmd?
body: <p>I recently updated my Git Extension to 3.0.2.5232 and now my git is no longer supported. When I run:</p>
  
  <pre><code>git --version 
  </code></pre>
  
  <p>I get</p>
  
  <pre><code> git version 2.9.0.windows.1
  </code></pre>
  
  <p>However, I can't just download the latest version of git online because I can't run an .exe installer due to admin rights and what not, so is there a command I can run to upgrade directly from admin cmd?</p>
