title: Warning about system root certificate pool crypto/x509
body: <p>I am having the following warning message when issueing docker commands: (ex: docker ps)</p>
  
  <pre><code>C:\Users\whha&gt;docker ps
  time="2017-01-24T23:17:36+01:00" level=warning msg="Unable to use system      certificate pool: crypto/x509: system root pool is not available on Windows"
  </code></pre>
  
  <p>Any idea how can it be avoided?
  I´m running docker using docker toolbox on windows 8.1.</p>
