title: How to update the entire Anaconda Python distribution offline in Windows?
body: <p>I use Anaconda Python distribution on a Windows machine without Internet access.</p>
  
  <p>The installation is extremely easy: just download and copy the Anaconda Windows installer and install in standard way.</p>
  
  <p>But when it comes to updating:</p>
  
  <ul>
  <li>If I manually download, copy, and update individual packages, it is tedious and prone to error, considering the complicated interdependency among packages.</li>
  <li>If I uninstall the entire Anaconda and then reinstall a new one (my current approach), I'll lose my personal configurations as well as manually installed packages that are not included in Anaconda installer.</li>
  </ul>
  
  <p>Is it possible to run something like:</p>
  
  <pre><code>conda update Anaconda-2.2.0-Windows-x86_64.exe
  </code></pre>
  
  <p>to extract and update necessary packages from the all-in-one Windows installer?</p>
  
  <p>I notice the new <code>--offline</code> option provided by the latest <code>conda update</code> command, but it doesn't seem to serve for this purpose...</p>
