Description:

Supports multiple languages and alternative method inputs in Windows and MS Office. The language bar is displayed alongside the System Tray if more than one keyboard layout is enabled (for switching input languages) or, for example, if speech is selected as an alternative input for MS Office or Notepad. Required to support advanced text services (such as right to left text) for East Asian users. Can be disabled via Start → Control Panel → Regional and Language Options → Languages → Text Services and Input Languages → Details → Advanced → System Configuration → Turn off advanced text services (which also turns off the language bar). See also here and here. Can also cause problems with some other programs if left enabled - see here for such an example
