It doesn’t matter if you’re upgrading Windows 8, Windows 8 Pro or Windows RT, or any of the preview versions of the operating system. The upgrade process to Windows 8.1 or Windows RT 8.1 are exactly the same. Though problems and errors that might happen could be different from device to device.
Every user running Windows 8 will receive a notification in the Windows Store, click Download and the upgrade to Windows 8.1 will begin, then after a few restarts and OOBE setup, you’ll be back in business once again.
Although the upgrade process is the same, the outcome will be a bit different if you’re running Windows 8.1 Preview because you’ll have to reinstall all your applications after the upgrade, which is not the case with Windows.
