Unable to add language pack from Windows 10 ADK/PE add-on to Windows 10 ISO

I'm going to answer my own question because I've figured out the issue.

tl;dr - If you want to customize the Windows 10 installer to be able to install Windows 10 in multiple languages, the Windows 10 ADK/PE add-on is probably not what you want.

Instead, acquire the language pack ISO for your Windows 10 release. The language pack ISO has Microsoft-Windows-Client-LanguagePack files, which are localisations for Windows 10.

The Microsoft-Windows-WinPE-LanguagePack files, which the ADK/PE add-on provides, are language packs for Windows PE. You can use them with the boot.wim file, not with the install.wim file.

Yes, the Windows 10 Enterprise evaluation ISO for 1809 is release 10.0.17763.107. The Enterprise evaluation ISO for 1903 is 10.0.18362.30.

Note that you do have to give "company details" to download the Enterprise evaluation ISO.

The issue preventing me from applying the language packs that ship in the Windows 10 ADK/Windows PE add-on is pretty obvious in hindsight:

The language pack that the Windows PE add-on installs are, as the name above implies, for Windows PE and not for Windows 10 the OS.

If you mount sources\boot.wim from the Installer ISO and try to apply the language packs installed by the Windows ADK/PE add-on, it works:

But try doing that with sources\install.wim and it doesn't work because the installer is not Windows PE.

No, not that I could find. At least not what I would reasonably consider "public"

If you want to apply language packs to the Windows 10 1809 installer, you should use your favourite search engine to look for mu_windows_10_language_pack_version_1809_updated_sept_2018_x86_x64_arm64_dvd_f17c743a.iso. It's ~5.9GB large and contains language packs for the x86, x64, and arm64 builds of Windows 10 (17763.1).

I was not able to find a Microsoft official source for this language pack ISO, however some file sharing sites have it available to download. You should be able to find a copy by searching for the ISO name above (at least, for Windows 10 1809).

The theoretical answer to this question, at least from my research, is no.

However the practical answer is yes. If you can find the above language pack ISO from a third party, you can use the Windows 10 October 2018 Update official ISO from Microsoft to add languages:

I'm not sure what one would do for 1903 or future Windows 10 releases. Determine the name of the language pack ISO and see if you can find a "public" source to download it from ¯_(ツ)_/¯
