revert from.ESD to .WIM so DISM will work
Many of your Windows users depend upon DISM repair so I suggest you revert to .WIM. .ESD can convert to .WIM but the level required to do so is above the majority of your users.
Windows 10 1803....no more install.wim file inside the ISO? Please publish official instructions for converting .ESD to .WIM using DISM, or update WDS component to allow importing *.esd files when importing searching for importing "install.wim". -DA
