i'd try building an ffu that supports hyper-v potentially as i have access to some parts of an oem site
I just wonder what it is that they will "release", isn't it just an OEM OS, delivered pre-installed on certain devices?
as far as I'm aware, they're not "releasing" 10X to the public technically (as an installable image), only device manufacturers, who should be receiving an OEM Preinstallation Kit at some point
Technically, wouldnt a (leaked) OEM Preinstallation Kit of Windows 10X be much more "comfortable", to be able to "set it up" for different machines and, for example, creating bootable USB thumb drives ? I only remember this from the days of Windows XP and Vista though, when such CDs/DVDs would (sometimes) be even part of the "disc collection" included in your purchased PC.
Go back to Win 95. Win 95 was released to the Public BUT Win 95 A, B, & C were released for OEM only. Full install. You could get the CD's and install your self.
