Change the display language

The display language is the language that Windows uses in wizards, dialog boxes, menus, Help and Support topics, and other items in the user interface. Some display languages are installed by default, and others require you to install additional language files. When you change the display language, it is changed for your user account and is not changed on the Welcome screen. If you want to set the display language for multiple users or the Welcome screen, see Apply regional and language settings to reserved accounts.

1. Open Regional and Language Options by clicking the Start button , clickingControl Panel, clicking Clock, Language, and Region, and then clicking Regional and Language Options.
2. Click the Keyboards and Languages tab.
3. Under Display language, choose a language from the list, and then click OK.

Note

If you don't see the list of display languages, you need to install additional language files first. For more information, see Install a display language.

When you change the display language, the text in menus and dialog boxes for some programs might not be in the language that you want. This happens because the program might not support Unicode. For more information about changing the text in menus and dialog boxes for programs that do not support Unicode, see Change the system locale.
