Enable a multilingual user interface in a Windows Server 2008 environment

Multilingual User Interface Language Packs (Windows Server Language Packs) enable a multilingual user interface in a Windows 2008 environment. Adding one or more language packs to a Windows Server 2008 image enables one or more languages in the installed Windows Server operating system, allowing corporations to deploy the same Windows Server 2008 image worldwide while still providing localized user interfaces.
