Hi Dio,
Microsoft has a dedicated business representation for this called the 'Microsoft Language Development Centre', part of the Microsoft development centre. These are located across the globe and are often attached to local Microsoft offices. Was there any particular centre or language that you were particularly interested in?
Here is the language team at the language office in Portugal (I think this office is the main focus for language development..... but don't quote me on that

)

Here are the Win 7 Language availability and specifics
Language Packs in Windows 7
If you are interested in employment, perhaps a look at the development centre site would help
