Windows 7 RTM x86 and x65 MUI language packs in DVD ISO format were leaked earlier from MSDN and TechNet Subscriber Downloads. User who prefers to download all language packs for Windows 7 via BitTorrent (BT), torrent is available for the MSND or TechNet DVD ISO versions.
Do take note that if too many additional language packs are installed, the disk space and system performance can be affected. In particular, disk space and system performance are affected during servicing operations, such as Service Pack installations, according to KB972813.
