to murphy78 ** The only difference between this one and v1 is the efi/boot folder which contains the bootx64.efi and some random boot files. These are usually transferred by rufus during the ufd gpt/fat32 process, but since I switched to split-wim, rufus doesn't know how to do it. I've put the files there manually so rufus won't bother trying to do that. If you don't use UEFI### u are use split-wim in windows8.1too are going to release windows8.1 v2 or not
