When you add language packs using DISM, the licensing requirements of how many language packs are allowed to run on the Windows edition are not verified. If you add multiple language packs, all non-default, non-user selected languages will be removed from the computer after a period of time. For more information, see Add Language Packs to Windows.
To add a language pack by using DISM
On the running operating system, open an elevated command-line prompt.
Type the following command to add a language pack to the operating system.
Dism /online /Add-Package /PackagePath:C:\test\LangPacks\lp.cab
