This restriction is used to set the language used in menus and dialog boxes in Windows and prevent users from changing it. When enabled the system disables the menus and dialog boxes in the Regional Options in Control Panel.

Open your registry and find or create the key below.

Create a new DWORD value called "MultiUILanguageID" and set it to a value from the table below to restrict the system to that language.
