I don't have any PT-BR versions (Brazilian Portuguese (PT-BR) is different from European Portuguese (PT-PT)). Of course, no one can stop you from finding them on archive.org, but my collection is different: I have some Bulgarian-language Windows versions, some English versions, and mostly Russian-language Windows versions, although English versions aren't excluded either (the beta builds confirm this).
It would not hurt to install another language pack in the standard editions of Windows Vista and Windows 7 using the Vistalizator program, having language packs!
