You can change the language Windows 7 uses to display text in wizards, windows, dialog boxes, menus, and other windows items in the user interface. Some display languages are installed by default on Windows 7, while others require you to install additional language files.
Before you can install a display language, you need access to the Windows 7 language files. These files can be found on your computer, a computer in your network, or your Windows DVD. They can also be downloaded from the web. For more information, see How do I get additional display languages?
