Re: Windows 8 to Win 8.1 Upgrade Key Issue
Sorry off on another tangent.
Biggles once you have the key and an image to install, get it done then follow the steps here to create your own recovery image :)
If you really wanted to you could install everything including apps and updates then create the image. Copy the create WIM file to a USB install disk for Windows 8/8.1 and replace Install.wim and you now have a backup.
