title: How to modify the PATH variable definitely through the command line in Windows
body: <p>I would like to make a .bat file that would add some string at the end of the value of the Windows PATH variable. Warning, I want this change to be definitive, not working only for the current session. </p>
  
  <p>Does somebody know of a way to do this ? As much as possible it should not be dependent on the version of Windows</p>
