title: Where does Java preferences API store the values under Windows?
body: <p>After saving some application preferences via java.util.prefs API, I cannot find them.
  This is a Windows 7 machine and I searched registry for the path <code>JavaFXApp1</code> and individual values I've saved such as <code>CurrentColor</code>, but found nothing.</p>
  
  <p>The values have been saved for certain, as the application reads them when it starts.</p>
  
  <p>Where does Java preferences API store the values under Windows? This is my saving and reading code:</p>
  
  <pre><code>Preferences prf = Preferences.userRoot().node("/JavaFXApp1");
  prf.putInt("CurrentColor", appCtrl.getIValue());
  
  Preferences prf = Preferences.userRoot().node("/JavaFXApp1");
  i = prf.getInt("CurrentColor", 0);
  </code></pre>
