After you run the OOBE wizard, Lpksetup.exe automatically removes the unused language packs. When it removes language packs, Lpksetup.exe compares language names instead of language codes. If a removed language and the current system language have the same language name, the current system language pack is also removed. For example, ZH-TW and ZH-HK share the name “Chinese”
