title: System (pid 4) process locks appdata
body: <ol>
  <li>Convert win32 desktop app using <code>Desktop App Converter</code>.</li>
  <li>Install app using generated appx.</li>
  <li>Launch it and exit.</li>
  <li>Not always, but very often, a strange thing happens: I can't modify/remove files from my original (non converted) app's %localappdata% folder. Files are in use by System (pid: 4) process. I have to uninstall appx to remove the lock.</li>
  </ol>
  
  <p>Is it a bug? </p>
  
  <p>Is there a workaround that does not require uninstalltion of Appx?</p>
  
  <p>Why does it lock these files at all? As far as I know - converted app must use its own copy of %localappdata%.</p>
