When building a Windows10 automation folder using bootwiz.exe, it fails in random places with a pop-up message "The Directory is not empty." and an ok button.
In some cases you can click OK and conitune but in certain cases the program freezes.
"The Directory is not empty."
ITMS 8.0
WinPE
Some missing right for the administrator roles prevented the DISM unmount from completing without error code.
This problem was resolved in ITMS 8.0 Hotfix 6.
