Hello!! I downloaded the leaked ISOs from MSDN, x86 and x64. Then I tried to boot them on a notebook with original uefi license. They boot as uefi but they ask me for a serial. As I know theese ISOs are the RETAIL versions. Am I right ?? Looking inside there is no EI.CFG. So, I made an EI.CFG, writing "OEM" string for "Channel", put the file on the "sources" folder then re-burn whole ISO again. Now, it starts as uefi, it asks me which version I want (Core or Pro), and no key needed (I think it reads it from uefi). Am I right again?? I tried another EI.CFG leaving black also "Channel" but it doesn't work, I got an error. Is there an option to have RETAIL and OEM inside an only 1 ISO ??
