title: Refresh cmd environment with a command
body: <p>I have a problem with a batch file I use to deploy software on new computers.<br>
  For example, I install <code>Python 2.7</code>, and next I would like to upload <code>pip</code> to install all libraries. My batch return the error <code>could not update pip , python is not recognize as internal command or batch</code>. I have to close the script and reopen it.</p>
  
  <p>Is there a way to refresh my cmd environment without closing it ?</p>
  
  <p>I am not English so I hope you will understand me.</p>
  
  <p>I am under <code>Windows 7 PRO 64 bits</code> and I use <code>cmd.exe</code>.</p>
