Difference Between Language Packs (LPs) And Language Interface Packs (LIPs)

Language Packs (LPs): Language Packs are available only for Ultimate and Enterprise edition of Windows 7. Language packs provide a translated version of Windows dialog boxes, menu items, and help content. Although there are ways to install Language Packs on Home Premium and Professional editions of Windows 7, we don’t recommend it.

Language Interface Packs (LIPs): LIPs are available for all editions (Starter, Home Basic, Home Premium, Professional, Enterprise, or Ultimate) of Windows 7. But LIPs only translate most common dialog boxes, menu items and help content. Unlike Language Packs LIPs are available to download via Microsoft Download Center. To install a language pack, you need to have the required parent language installed on your PC.

Over 55 language packs are available to download via Microsoft Download Center. You can find the full list of LIPs here.
