If you would like to run Windows 7 in any of these 5 South African languages then you can now download them from the Microsoft download center:

Please note that the South African Windows 7 LIPs can only be installed on a system that runs an English client version of Windows 7.   They are available to download for both 32-bit and 64-bit systems.

You can also download these language interface packs for Windows Vista and some (Africaans, Setswana and isiZulu are available for to download Windows XP)
