I am trying to activate a Windows 10 IoT Enterprise CBB install permanently with its license key by using the DISM tool.
I have found this topic which explains how to do it (mounting the install.wim, setting the product key and unmounting the install.wim). I am doing the same steps, however when installing Windows to a drive, it still prompts me the Product Key dialog box also with EULAs.
My product key is valid and the purpose of this operation is to install my Windows 10 Edition in "one-shot" which means without typing any license key or accepting any EULAs since they would have been already typed/accepted.
(I am using a bootable USB drive in UEFI)
