title: Docker now giving an error after updating
body: <p>After using Docker for almost two months, today I got the following error:</p>
  
  <blockquote>
    <p>C:\Users\dell>docker --version
    Docker version 17.06.0-ce, build 02c1d87</p>
    
    <p>C:\Users\dell>docker ps -a
    error during connect: Get <a href="http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.30/containers/json?all=1" rel="nofollow noreferrer">http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.30/containers/json?all=1</a>:
    open //./pipe/docker_engine: The system cannot find the file
    specified. In the default daemon configuration on Windows, the docker
    client must be run elevated to connect. This error may also indicate
    that the docker daemon is not running.</p>
  </blockquote>
  
  <p>Yes, the daemon is running, or at least it is shown as running under Services. I use it only with a local container and do not do anything remote.</p>
  
  <p>Any suggestions on how this can be solved?</p>
