title: After the desktop bridge app is uninstalled, ProgramData\Packages\{appName} still has a folder "S-1-5-21-****"
body: <p>I found that after my app was installed, the <code>S-1-5-21-***\SystemAppData\Helium</code> folder was automatically created under <code>ProgramData\Packages\{appName}</code>, and there was also a cache folder and two dat files.</p>
  <p>So, how to Ensure that all contents of the app will be deleted after uninstalling?</p>
