The current EasyRE demo video lists a partition /dev/sda1, a *nix layout.It is true that MS stops companies from distributing their software permission and it is also know the cases of allowing companies to sell Windows PE in return of a commission for each sale. See for example Winternals (before being acquired) or NeoSmart with their ready-made boot disks: https://neosmart.net/EasyRE/
Hence I doubt distributing Windows PE currently, no idea about real contents.
Yes, neosmart offered a Windows PE to buy in the past.

Did MS stop neosmart to redistribute a builted PE?
