Use Import-OSMedia to import all Windows Editions you plan to include. Its best to sort by EditionId as some languages may have the Image Name spelled differently

This process will take about 5-10 minutes per OS, so give it some time. When complete, all Operating System Languages will be imported into OSMedia. Windows 10 en-US does not show a language by default

Update-OSMedia (Base Language Only)

The Base Language OS will need to be updated with Update-OSMedia. It is not necessary to update the additional Languages
