Hi, it's not about additionally installed language packs (e.g. language packs in .cab files). It's about what Windows has probably buried deep inside the .wim file :/ Like: Japan Traditional Chinese etc. WinReducer, NTLite and all these tools have an option to remove those superfluous language files. I'd like to remove those files by dism itself, not by using any of such tools. How do I get their package names with dism?
