How to force your Windows (RT) 8.1 Upgrade
by Volker Weber
The Windows Store is a bit "unresponsive" today. It should present you with an upgrade option, but it did't for me. If you want to upgrade from 8.1 Preview or 8.0, just copy this string into the Internet Explorer URL bar:
ms-windows-store:WindowsUpgrade?ocid=GA8-1_O_WOL_Hero_Home_81Update_Pos1_01
It should open the appropriate page inside Windows Store. You can take it from there.
