Not able to run the default hello-world program in docker on Windows 7
<p>I just finished installing Docker on my Windows 7 machine using the instructions provided here <a href="https://docs.docker.com/windows/step_one/" rel="nofollow noreferrer">https://docs.docker.com/windows/step_one/</a>.</p>

<p>During the installation I did not install <code>Git</code> and <code>Virtual Box</code> as I already had them installed on my machine. After installation I fixed the missing <code>bash.exe</code> script issue and got docker working to some extent. But I am not able to run the default <code>hello-world</code> docker command. I am getting following error.</p>

<p>I already looked into similar issue mentioned on SO <a href="https://stackoverflow.com/questions/32597597/troubleshoot-docker-on-windows-attempt-to-run-hello-world">Troubleshoot Docker-On-Windows attempt to run hello-world</a> but the error that I am getting here is different. So please do not mark this as duplicate.</p>
