1. What steps are you using to create multi lingual image?
Setup clean 1809 to test adding the languages on a VM.
 
2. What languages are you adding to the image?
We're trying to add de-de, it-it, ja-jp, sv-se, and zh-cn. Using the cab files from the most recent Windows 10 Language Pack ISO. All of these should be SKU languages.
 
3. Which version of the OS are you trying to create the image on (1803, 1809 etc.)?
1809
 
4. What steps in the workflow are not working / are inconvenient?
Adding the languages from language settings, within Windows, causes sysprep to fail. Injecting the languages with DISM, online and offline, doesn't seem to do anything, as they still seem to have to download. They inject successfully but when tested on a machine the languages are not there. We also need the, "Basic Typing", keyboard layouts that are associated with the languages which also causes sysprep to fail.
 
5. Are you trying to create image for new machines or upgrading the OS on existing machines?
Image for new machines
