As you may already know from previous articles, Windows 10 supports changing the display language using language packs. If you are working in a localized user account in Windows 10 which is your native language, you might want to find out what the default system language of the operating system is. There are several methods to find this information.
The default language of the user interface (system language) is the language used during the installation of Windows 10. When installing and right after installing, Windows 10 uses this language to show messages, buttons and menus. The user can change this language to another one by installing a language pack if the current edition of Windows 10 supports MUI. Tip: See how to find the edition of Windows 10.
