title: Private Docker Registry: 'x509: certificate signed by unknown authority' only for Windows images
body: <p>While trying to pull Windows images from a Private Docker Registry, I'm getting the following error</p>
  
  <pre><code>x509: certificate signed by unknown authority
  </code></pre>
  
  <p>I've installed the proper certificate and I can pull Linux images without any issue, but for some reason I'm unable to pull Windows ones.</p>
  
  <p>My co-workers don't have this problem.</p>
  
  <p>Any ideas on this one?</p>
