Windows Vista supports companies that need to equip their users to work with various languages or in multiple locale settings. This includes organizations that:
Operate internationally and must support various regional and language options, such as time zones, currencies, or date formats.
Have employees or customers who speak different languages, or require language-dependent keyboards or input devices.
Develop an internal line of business applications to run internationally or in more than one language.
If you have roaming users who need to log on anywhere and edit a document in several languages, you need the appropriate language files installed or installable on demand, on a server or workstation. You can also use Terminal Services to allow users to initiate individual Terminal Services sessions in different languages.
