Question: what is a mui file in windows 7

title: Multilingual User Interface
text: Functionally , MUI packs for a certain product perform the same task as localized versions of those product , but with some key technical differences . While both localized versions of software and MUI versions display menus and dialogs in the targeted language , only localized versions have translated file and folder names . A localized version of Windows translates the base operating system , as well as all included programs , including file and folder names , objects names , strings in registry , and any other internal strings used by Windows into a particular language . Localized versions of Windows support upgrading from a previous localized version and user interface resources are completely localized , which is not the case for MUI versions of a product . MUI versions of a product do not contain translated administrative functions such as registry entries and items in Microsoft Management Console . The advantage of using MUIs over localized versions is each user on a computer could use a different language MUI without requiring different versions of software installed and dealing with the conflicts that could arise as a result . For example , using MUI technology , any version of Windows can host Windows applications in any other language .
