title: Windows 10 - system environment variables (Path vs. PATH)
body: <p>I'm learning java, and had the jdk set as part of the <code>Path</code> system variable.
  When following a guide on how to install Maven, I created a <code>PATH</code> variable and set again the jdk to the <code>PATH</code> variable.</p>
  
  <p>The result was that the <code>Path</code> variable was deleted from the system (Windows 10).
  In addition, the jdk and jre were also deleted from the location where they were installed (<code>C:\Program Files\Java</code>).
  I reinstalled the jdk and jre, and defined a new <code>PATH</code> variable. for now, I can run java and eclipse, and did not experience any issues.</p>
  
  <p>My questions:</p>
  
  <ol>
  <li>Is there any difference between <code>PATH</code> and <code>Path</code>?</li>
  <li><code>Path</code> variable had many programs set to it (I don't remember which programs). Now that it no longer exists, what would be the implications?</li>
  <li>What could be the reason that <code>Path</code> variable was deleted?</li>
  </ol>
  
  <p>Thanks,
  Oren</p>
