Docker を Docker Desktop Installer を使ってインストールしました。  
その後コンテナを起動しようとして Windows PowerShell で下記のコマンドを実行するとエラーが発生する。  
処置方法について教えていただけませんか？

```

    PS C:\Windows\system32> docker run hello-world
    C:\Program Files\Docker\Docker\resources\bin\docker.exe: 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 'C:\Program Files\Docker\Docker\resources\bin\docker.exe run --help'.

Windows10の環境で docker コマンドを実行するとエラーが発生する
おそらく Docker Desktop が起動していません。

スタートメニューから「Docker Desktop」を探し、起動してください。

<https://docs.docker.com/docker-for-windows/install/>
