In Windows 10, you can change the display language. For example, if you have a PC with an English version of Windows 10, but your native language is not English, you can convert the operating system into your native language without reinstalling. Today, we will see how to force System UI language as a display language for all users in Windows 10.

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.  It is also possible to have a different display language for each user account.

You can lock the language options and force all users to use the system UI language as their display language. Here is how.

    Set it to 1 to force the system UI language as a display language in Windows 10.
  4. To make the changes done by the Registry tweak take effect, you need to restart Windows 10.
