Editing Multilingual User Interface (section)

== History ==
MUI was introduced with [[Windows 2000]] and is supported in each subsequent Windows release.

=== Windows 2000 and Windows XP ===
MUI products for these versions were available only through volume agreements from Microsoft. They were not available through retail channels. However, some [[Original equipment manufacturer|OEM]]s distributed the product.{{Citation needed|reason=Which OEMs include such a feature that's usually available on volume licensing of XP/2000?|date=October 2022}}

==== Languages in Windows XP ====
Up to [[Windows XP]], MUI packs for a product are applied on top of an English version to provide a localized user experience. There are a total of 5 sets of MUI packs.

=== Windows Vista ===
[[Windows Vista]] enhanced MUI technology to separate the English resources from the application logic [[binary file]]s. 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 [[Windows Ultimate Extras|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:

=== Windows 7 ===
MUI is available to [[Windows 7]] Enterprise and Ultimate edition users, as well as Windows Phone 7.

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).<ref>{{cite web|title=How To Install Language Packs In Windows 7|url=http://www.thewindowsclub.com/how-to-install-language-packs-in-windows-7|url-status=live|archive-url=https://web.archive.org/web/20100801043244/https://www.thewindowsclub.com/how-to-install-language-packs-in-windows-7|archive-date=1 August 2010|access-date=29 April 2016|publisher=[[The Windows Club]]}}</ref>

=== Windows 8/8.1/RT ===
Beginning with Windows 8/RT, most editions of Windows are able to download and install all Language Packs,<ref>{{cite web|title=Language packs are available for Windows 8 and Windows RT|url=https://support.microsoft.com/en-us/kb/2607607|access-date=29 April 2016|publisher=[[Microsoft]]}}</ref> with a few exceptions:

* In Single Language editions of Windows, only one language pack is allowed to be installed, <ref>{{Cite web|title=Check whether your version of Windows supports multiple languages|url=https://support.microsoft.com/en-us/windows/check-whether-your-version-of-windows-supports-multiple-languages-eaf060a6-3642-4612-6b75-b34e57a08abf|access-date=2022-01-10|website=support.microsoft.com}}</ref> 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]]<ref>{{Cite web|last=Blog|first=Windows Experience|date=2011-07-06|title=Windows Phone around the world: Language support in Mango|url=https://blogs.windows.com/windowsexperience/2011/07/06/windows-phone-around-the-world-language-support-in-mango/|access-date=2022-01-10|website=Windows Experience Blog|language=en-US}}</ref> and PCs as of [[Windows 8]] (since Windows 8 and [[Windows Phone 8]] share the same Windows NT kernel) and was later dropped in Windows 10 version 1803, but was later quietly reinstated as of Windows 10 version 1809. An end user could install a retail license on top of an OEM license by performing a clean install through the Media Creation Tool to circumvent the region locking and install any display language that they want.
**The Windows update process does not affect the currently installed display languages in any way, but it may give the end user access to newly released language packs made available by the OEM (PCs only). However, when installing a new feature update, it may change the display language back to the one set during the initial setup process. For example, if the Samsung ATIV Smart PC on AT&T is upgraded from Windows 8.1 to Windows 10 Anniversary Update (not necessarily done in one go), it will now be able to install Portuguese (Brazil), Vietnamese, Chinese (Simplified and Traditional), and Japanese in addition to English, Spanish, French, German, Italian, and Korean (the last three languages can be downloaded by the end user at the time of its launch), just like with the Galaxy S8 series and the Verizon-based Galaxy Book.
**On the other hand, a Samsung Galaxy Book device does not support Afrikaans as a display language, because Samsung apps do not officially support Afrikaans.<ref>{{Cite web|title=Get Samsung Notes|url=https://www.microsoft.com/en-us/p/samsung-notes/9nblggh43vhv|access-date=2022-01-10|website=Microsoft Store|language=en-us}}</ref> Furthermore, cellular variants of the Galaxy Book laptops sold in North America support fewer display languages than their Wi-Fi-only counterparts, just like on their smartphones.
**Certain language packs like English (Australia) and English (Canada) are only supported on the Xbox consoles and the Surface Duo.
**Some LIP packs require certain MUI packs (base languages) to be present or compatible.<ref>{{Cite web|title=Language packs for Windows|url=https://support.microsoft.com/en-us/windows/language-packs-for-windows-a5094319-a92d-18de-5b53-1cfc697cfca8|access-date=2022-01-11|website=support.microsoft.com}}</ref> If that base language is not present or compatible, then that LIP cannot be installed on that device.

=== Windows 10 ===
Beginning with Windows 10 version 1803, Microsoft started using the term "Local Experience Pack" (LXP) in some places [store?] instead of the older term "Language Pack", but they work the same way.<ref>{{Cite web|date=2018-11-14|title=Local Experience Packs: What are they and when should you use them?|url=https://techcommunity.microsoft.com/t5/Windows-IT-Pro-Blog/Local-Experience-Packs-What-are-they-and-when-should-you-use/ba-p/286841|access-date=2022-01-10|website=TECHCOMMUNITY.MICROSOFT.COM|language=en}}</ref> In addition to installing via Windows Settings, these 110 LXPs are also available through the Microsoft Store (app and web); the latter enabling remote installation for consumer editions of Windows.<ref>{{Cite web|title=Local Experience Packs|url=https://www.microsoft.com/en-us/store/collections/localexperiencepacks?cat0=devices|access-date=2022-01-10|website=Microsoft Store|language=en-us}}</ref> As with all applications from the Microsoft Store, only the LXPs that are compatible with that Windows device are shown in the Microsoft Store app. 

An LXP is updated through the Microsoft Store; outside of the normal Windows update cycle.<ref>{{Cite web|title=Local Experience Packs|url=https://support.microsoft.com/en-us/windows/local-experience-packs-4cf70f83-bc24-00bc-8bc5-420d22963fef|access-date=2022-01-11|website=support.microsoft.com}}</ref>
