title: docker error during connect - deamon is not running on Windows 10
body: <p>I am using Windows 10 pc. Recently I have downloaded docker for Windows and it was working fine. But, recently a problem occurred and is it not start anymore it just hang in the status starting. </p>
  
  <p>I haven't changed any configuration and I am wondering what may cause this problem. </p>
  
  <p>I use the latest version of docker.</p>

  <p>On my pc, Hyper-V is enabled and Containers are disabled. (Since, I son't use Windows container, I don't think it is necessary. )</p>

  <p>when I try docker command on powershell. It could not found docker command. </p>
  
  <p>I am not in an urgency to set up docker, I was just playing with it. But, suddenly this problem occured. I have been trying to solve this problem for a while. I have search similar problems and uninstall docker several times while searching for a solution. It is wierd and disturbing that a tool suddenly stop working and there is no trace to find the root problem. I suspect may be company sucurity policy change effects my computer and cause this problem But I could not find any clue to support this.</p>
  
  <p>My question is what should I do to understand what is wrong. What cause the problem and how can it be fixed.</p>
  
  <p>Note: When I restart computer following error occurs.</p>
