title: Git is not recognized in Windows gitlab ci
body: <p>I configured a gitlab runner as explained here: <a href="https://docs.gitlab.com/runner/install/windows.html" rel="noreferrer">https://docs.gitlab.com/runner/install/windows.html</a></p>
  
  <p>Unfortunately, when I push to my repository, my pipeline fails:</p>
  
  <pre><code>Running with gitlab-runner 10.5.0 (80b03db9)
    on windows runner 79cb4019
  Using Shell executor...
  Running on WINSTD-45-13...

  ERROR: Job failed: exit status 9009
  </code></pre>
  
  <p>When I open the command line utility as administrator, <code>git</code> is available.</p>
  
  <p>Any idea why <code>git</code> is not recognized whithin the pipeline script?</p>
