How to Force System UI Language as Display Language in Windows

The display language a user selects changes the default language the entire operating system uses for that specific user account.

The system UI language is a user interface language that can be set by an administrator in the Welcome screen and new user accounts settings. Windows uses this language if the current user (ex: new user) has not made specific language settings or if no active account is signed in like on the Welcome, Sign In, Sign Out, Shutdown, and Restart screens. The system UI language can be changed only if more than one user interface language (aka: display language) is installed on the computer.

If you like, you can enable a group policy setting to force the selected system UI language to be used as the display language for all users preventing them from being able to change their display language.

This tutorial will show you how to enable or disable forcing the system UI language to be used as the display language for all users in Windows 7, Windows 8, and Windows 10.

You must be signed in as an administrator to force the system UI language to be used as the display language.
