Few days backs Microsoft released the first Release Candidate of Windows 7 Service Pack 1 (SP1) build 7601.17105 to testers. It seems Russian site Wzor has leaked “Windows 7 and Windows Server 2008 R2 SP1 RC build 7601.17105.100929-1730″ and is now available for download in several file sharing sites and Bittorrent sites.
Update [31/05/2016] : If you are looking to download Windows 7 / Windows 8 ISO images easily, then use this free & tiny tool called Windows ISO Downloader.
The Windows 7 SP1 RC is available for both 32-bit and 64-bit versions, the 32-bit versions weighs 337 MB and 64-bit version is about 614 MB in size.
This RC is currently available in English, French, German, Japanese and Spanish. According to build string “7601.17105.100929-1730“, it indicates that the current build was compiled on 29 September at 5.30 PM.
