title: RemoveError: 'setuptools' is a dependency of conda and cannot be removed from conda's operating environment
body: <p>I have Win 10</p>
  
  <p>When running:</p>
  
  <pre><code>conda update conda
  </code></pre>
  
  <p>I encountered this error:</p>
  
  <pre><code>RemoveError: 'setuptools' is a dependency of conda and cannot be removed from
  conda's operating environment.
  </code></pre>
  
  <p>Nothing seems to help</p>
  
  <p>I tried to uninstall anaconda and got a successful message but it seems there are some traces of older version that still persist</p>
  
  <p>How can I completely erase all traces of Anaconda installation?</p>
