Docker Error Docker daemon is not running

Question

When I try to do docker run -d -p 80:80 docker/getting-started on Windows 10 Pro, I receive an error message.

docker: error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.40/containers/create: 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. See 'docker run --help'.
