With Windows 10, version 1803, we started to deliver language translation improvements via Local Experience Packs, also referred to as LXPs. Local Experience Packs are AppX packages delivered via the...
There are some differences in W10 1903 and W10 Before. The LP.cabs are avail in the VLC NOT in the OS-Selections (Left side:"Windows", they are in "Software Assurance".) It is clear that you have the correct license for your Company.
Download the LP's and integrate the LP's (and "Features on Demand") for your languages.
e.g: en-US and de-DE
We use always a en-US OS as a Base OS. Take the en-US-install-wim and integrate the LP's anf FOD's with DSIM. Mount the Image Enable the Netfx3 and IE with DSIM: (c:\temp\1903_sxs is the sxs folder from the 1903 ISO) dism ... /enable-feature /featurename:NetFx3 /source:C:\Temp\1903_sxs
Add the LP's (C:\Temp\1903_LP have a copy of the needed FULL UI's) dsim .... /add-package /packagepath:C:\Temp\1903_LP\Microsoft-Windows-Client-Language-Pack_x64_en-us.cab
Use the "System Image Manager" and create a new unattend.xml ( for each language), in my case there are 2 xml's (de and en. Add all the packages you inseted to the Image and configure them as "permanent" Hide the Wireless Setup in oobe
Config the languages with "Microsoft-Windows-International-Core"
Here some parts of the XML for de-AT (German UI and Locale AT)
In 1903: if you do NOT add the 2nd KeyBD (en-US), the User has to download the "Local Experience Pack" even if the pack is added to the Image...(the LocalExperiencePack will be DOWNLOADED, so the USer has to have an Internet Connection)
Add a Collection variable to the EN and the DE ComputerCollections and query them in the Taskseq. You can use a priority for this variable if a computer is in both collections
in each "Apply OS" set the correct unattend.xml.
don't Forget to adjust the Timezone Settings for each language
To be sure that the FOD's and LP's are inserted i added the FOD's and LP' in the Taskseq. additionally. I did not test it if i don't do it. (no query of Collection variable).
After the Installation a Computer which is in the Collection of the DE-Clients, the UI is in DE, a "User" can Change to EN UI if he wants (no admin creds necessary)
