title: conda create --name py36 python=3.6 frozen
body: <p>I'm trying to upgrade python 2.7 to python 3.6 in anaconda via</p>
  
  <pre><code>conda create --name py36 python=3.6
  </code></pre>
  
  <p>However, it's been stuck at this for 10 minutes:</p>
  
  <pre><code>(base) C:\WINDOWS\system32&gt;conda create --name py36 python=3.6
  Collecting package metadata (current_repodata.json): done
  Solving environment: done
  </code></pre>
  
  <p>I tried it while running as administrator and while not running as administrator and I get the same result either way.</p>
  
  <p>Also, I'm using a Windows 10 PC.</p>
  
  <p>This is what I get when I enter conda info.</p>
