Once activated, the selected language becomes the default language for all system settings, dialogs, and even Office settings.
For Office to recognize the language, it needs to be included in the pre-installed Office version. If that’s not the case, you may have to install the missing Office language pack to activate it for documents and displays.
The keyboard language is also adapted when you modify the language in Windows. This is important when using Office, because you may find that your keyboard layout no longer matches the language setting. You can change the keyboard language settings in the Windows task list on the bottom right.
In Office, the language of the user interface (menus and push buttons), spell-check and grammar, and processing (keyboard language) can be personalized from the Office menu independently of the Windows operating system settings. Each feature could be set to a different language if desired.
