title: Unable to copy to Windows container ('docker cp') on Windows 10
body: <p>I set up Docker for Windows on my laptop and switched from <em>Linux Containers</em> to <em>Windows Containers</em> in Docker's settings (which prompted a couple of restarts and Windows updates). I pulled an image and ran a container based on it using the commands:</p>
  
  <pre><code>docker pull microsoft/dotnet-framework
  docker run -it microsoft/dotnet-framework cmd
  </code></pre>
  
  <p>In a second terminal window, I executed the command:</p>
  
  <pre><code>docker cp app container_id:/
  </code></pre>
  
  <p>and received this error message:</p>
  
  <blockquote>
    <p>Error response from daemon: filesystem operations against a running Hyper-V container are not supported</p>
  </blockquote>
  
  <p>I googled this error, but nothing (explanatory) came up, quite surprisingly. Is there a way I can run the image as a Windows container rather than a Hyper-V container, on Windows 10?</p>
  
  <p>Ultimately, I will deploy this container to a Windows Server 2016 host, but I need to do all development and testing in my laptop running Windows 10 Pro.</p>
