title: Docker command not available on Windows 7
body: <p>So I am using Docker with <code>boot2docker</code> for quite some time on Windows, and everything works ok. Recently, it started bothering me that in order to run docker commands, I have to start <code>Boot2Docker</code> terminal, and type there <code>boot2docker ssh</code>, and from virtual machine run docker commands. What I find strange is that after starting Boot2Docker terminal(without ssh-ing into vm), this is the output:</p>
  
  <pre><code>initializing...
  Virtual machine boot2docker-vm already exists
  
  starting...
  Waiting for VM and Docker daemon to start...
  .o
  Started.
  Writing C:\Users\user\.boot2docker\certs\boot2docker-vm\ca.pem
  Writing C:\Users\user\.boot2docker\certs\boot2docker-vm\cert.pem
  Writing C:\Users\user\.boot2docker\certs\boot2docker-vm\key.pem
  
  To connect the Docker client to the Docker daemon, please set:
      export DOCKER_HOST=tcp://192.168.59.103:2376
      export DOCKER_CERT_PATH='C:\Users\user\.boot2docker\certs\boot2do                      cker-vm'
      export DOCKER_TLS_VERIFY=1
  
  
  IP address of docker VM:
  192.168.59.103
  
  setting environment variables ...
  Writing C:\Users\user\.boot2docker\certs\boot2docker-vm\ca.pem
  Writing C:\Users\user\.boot2docker\certs\boot2docker-vm\cert.pem
  Writing C:\Users\user\.boot2docker\certs\boot2docker-vm\key.pem
      export DOCKER_HOST=tcp://192.168.59.103:2376
      export DOCKER_CERT_PATH='C:\\Users\\user\\.boot2docker\\certs\\bo                      ot2docker-vm'
      export DOCKER_TLS_VERIFY=1
  
  You can now use `docker` directly, or `boot2docker ssh` to log into the VM.
  </code></pre>
  
  <p>After that, I can run <code>boo2docker.exe ssh</code>, and from vm docker command. However without ssh-ing:</p>
  
  <pre><code>$ docker.exe
  bash: docker.exe: command not found
  </code></pre>
  
  <p>Am I missing something?</p>
