The final release of Windows 7 will include 50 new fonts and it will be the first version of Windows to ship with more fonts for non-Latin scripts than for Latin-based scripts. One of the major change is for the languages of India. To the nine fonts for Indian languages that was available in Vista, Windows 7 adds forty more. Windows 7 will now include multiple fonts for each of the official languages of India.

Windows 7 localized versions will be available within 2 weeks of the final release of Windows 7. Windows 7 will be released in 36 languages in October.

In addition to the 36 languages that will be released in October, there will be additional languages available for download as Language Interface Packs (LIPs) onto any Windows 7 edition as part of the Local Language Program (LLP). Catalan and Hindi LIPs will be available for download in October.

Windows 7 will also feature themes, backgrounds and sounds for local markets. Local Packs provide customized Windows 7 visual themes for a specific region. These visual themes contain locally relevant wallpaper images, custom aero glass colors, and regional sound schemes.
