Report Windows 10 1703 LanguagePacks in Windows 10 Posted March 11, 2018 So did you figure it out already? We're also doing some tests with multi-language images. In our case up till now we used the dutch media for Windows 10 1709 and in the reference image I injected the english language pack and features on demand such as OCR, text to speech etc. I managed to get a working deployment of a system where the image language was based on Dutch with the English language pack installed and applied after logging on. We'd also like a deployment where the base language is Dutch but with the English language pre-installed so users can easily switch. For some reason only the Dutch language is visible under languages and not the English. Users still have to add it themselves. The next obvious step is to not use the NL base image but use the English-US version instead, add the NL language pack and make sure that after logging in everything is in Dutch. Will try that scenario later this week. To me it seems the dutch media is just a English-US media with the Dutch language pack injected because when you check 'dism /online /get-intl' with dutch language based media and injecting the English-US language pack, this is what you get. Language Options So... using a dutch based media, injecting the english-US language pack in the reference image and using a customized unattend.xml does the trick when wanting to switch from NL to EN but when choosing to have the OS in NL the extra injected language pack en-US is not pre-installed. I've tried several methods for installing language packs including the one in the guide on this site (using offline language packs installation) but it still does not give me the results I want. Been struggling for some time now and it seems I am going around in circles so I'd appreciate your input on this since it seems you are trying to achieve the same thing.
