You may want to get rid of a built-in Windows 8 app such as News, Sports, et al. This is normally a straightforward operation – right click the app from the Start screen and choose Uninstall. In some cases your app can get stuck in a staged state. This can happen if you have pending updates for that application in the Windows Store.

A staged Windows 8 app will show {S-1-5-18 [Unknown user]: Staged} for the PackageUserInformation if you run get-appxpackage –allusers from within PowerShell.

Follow these steps to resolve the problem and remove the app completely:

  1. Install the update from the Windows Store
  2. Right-click the app from the Start screen and choose Uninstall
