SystemLocale specifies the default language to use for non-Unicode programs.

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

The system locale specifies which bitmap fonts and code pages (ANSI or DOS) that are used on the system by default. The system locale setting affects only ANSI (non-Unicode) applications. The language for non-Unicode programs is a per-system setting.

Users can change the system locale by using the Administrator tab in the Regional and Language Options Control Panel.


This setting can only be applied during the specialize and oobeSystem configuration passes. To specify language and locale settings during the windowsPE pass, see the SystemLocale setting in the Microsoft-Windows-International-Core-WinPE component.

For the list of supported languages, locales, and identifiers, see Supported Language Packs and Default Settings.

If this value is configured in the oobeSystem configuration pass, the Regional Settings page of Windows Welcome will be skipped.



Specifies the locale of the system.

System_locale is a string based on the language-tagging conventions of RFC 3066. The pattern language-region is used, where language is an ISO-639 language code and region is an ISO 3166-1 country or region identifier (for example, en-US, fr-FR, or es-ES).

This value is not case sensitive.

This string type supports empty elements.
