I have a "CoreConnected" aka "with Bing" Windows 8.1 laptop from walmart that is full of software I don't want and has a horrible recovery system. I was hoping to install virgin windows 8.1 from a MSDN iso and used en_windows_8.1_with_update_x64_dvd_4065090.iso which installed the professional version and didn't take the authentication key I had extracted from the bios. I made an ei.cfg to tell it to install the Core edition which installed, but that was when I learned that I actually needed CoreConnected for my key to work. I edited EditionId to be CoreConnected, and the installer complained that this EditionId didn't exist. Do I have to wait for Windows 8.1 with Update 2 before I can install CoreConnected fresh? Is there some other MSDN iso that contains CoreConnected?
