Multilingual User Interface (MUI) in Windows 7/8/10

Multilingual User Interface (MUI) is used either in a Windows 10/8, Windows 7, Windows Vista deployment scenario or on a local computer when the user changes language support. The benefits of MUI are more significant in the Windows deployment phase, particularly in multinational organizations.

Multilingual User Interface (MUI)

Configure Country, Region and language options:

You can use the Regional and Language Options settings in Control Panel to configure input languages for user accounts. For the MUI Pack, use these settings to specify or change the default user interface language or to install or remove user interface language packs.

Change the language for non-Unicode programs

  1. Log on as an Administrator.
  2. In Control Panel, click Regional and Language Options.
  3. Click the Advanced tab, and then under Language for non-Unicode programs, select the language for which the application was developed.

Simplify multiple language usage on desktops

Administrators can configure desktops to simplify working in multiple languages. For example, you can add a language toolbar to the desktop or a language icon to the taskbar, making it easier for users to change between different input languages when they need to compose documents in multiple languages. You can also enable specific key sequences that let users quickly change between installed input languages and alternative keyboard layouts and IMEs.

  • In Control Panel, under Clock, Language, and Region, click Change keyboards or other input methods.
  • Click Change keyboards, and then click the Language Bar tab.
  • In the Text Services and Input Languages dialog box, under Preferences, click Language Bar.
