Estonian Croatian Latvian Lithuanian Romanian Slovak Slovenian Thai Windows Vista Windows Vista enhanced MUI technology to separate the English resources from the application logic binary files. The application logic files are now language-neutral a.k.a. language-independent. In other words, the application logic files are no longer English-centric. This separation allows for changing languages completely without changing the core binaries of Windows, and to have multiple languages installed using the same application logic binaries. Languages are applied as language packs containing the resources required to localize part of or the entire user interface in Windows Vista. MUI packs are available to Windows Vista Enterprise users and as an Ultimate Extras to Windows Vista Ultimate users. Beginning with Windows Vista, the set of associated MUI APIs are also made available to developers for application development. [This allows anyone to use the MUI technology?] At launch, the following 16 language packs were released: Danish German English Spanish French Italian Dutch Norwegian Portuguese (Brazil) Finnish Swedish Russian Korean Chinese (Simplified) Chinese (Traditional) Japanese On October 23, 2007, the remaining 19 language packs were released: Czech Estonian Croatian Latvian Lithuanian Hungarian Polish Portuguese (Portugal) Romanian Slovak Slovenian Serbian Turkish Greek Bulgarian Ukrainian Hebrew Arabic Thai Windows 7 MUI is available to Windows 7 Enterprise and Ultimate edition users. Beginning with Windows 7, Microsoft started referring to a "MUI pack" as a "Language Pack"; not to be confused with a Language Interface Pack (LIP). Windows 8/8.1/RT Beginning with Windows 8/RT, most editions of Windows are able to download and install all Language Packs, with a few exceptions: In Single Language editions of Windows, only one language pack is allowed to be installed, the same behavior as editions of Windows 7 and earlier that are not Enterprise or Ultimate. In OEM editions of Windows, the exact language packs that are preinstalled/available for download depend on the device manufacturer and country/region of purchase (and the mobile operator for devices with cellular connectivity). This is a mixture of a local-market feature and a feature for everyone everywhere. There may be multiple display languages preinstalled on the device by the manufacturer and/or wireless carrier, but each manufacturer and/or wireless carrier installs two different sets of languages: one set of preloaded languages and one set of languages that can be installed by the end user. This rule is currently used in Windows Phones as of Windows Phone 7 and PCs as of
