The user interface of Windows 7 can be translated and converted to another language, with the use of a language pack, commonly known as MUI (Multilingual User Interface) or LIP (Language Interface Pack). With language pack, text in wizards, dialog boxes, menus, and other components in the Windows 7 UI can be converted into another display language from the default display language installed.

Additional language packs for supported editions of Windows 7 (i.e. Windows 7 Ultimate and Windows 7 Enterprise) can be downloaded via Windows Update, from MSDN and TechNet Subscriber Downloads section, or by downloading the leaked lp.cab cabinet files or LIP’s ISO images that float in Internet. If you manage to download additional language pack cabinet files, use the following how-to guide to install the new display language.

Note: If you downloaded a DVD or CD ISO image, extract the lp.cab file from the image first. This guide assumes that you’re not using Windows Update to download and install the language pack, which will be done automatically.
