This setting is used by Windows® Setup and Windows Deployment Services.

For a list of supported languages, see Supported Language Packs and Default Settings.

In upgrade installation types, this setting is ignored. In upgrade installations, you can upgrade only from the same language.

This value is not case-sensitive.

This string type supports empty elements.
