Windows 7 Service Pack 1 (SP1), or KB976932, was confirmed as being pre-released to OEM manufacturers on February 9, 2011. The build had leaked to the Internet around January 14th. The official Windows Team Blog confirmed authenticity of build 1850 as the final RTM ("release to manufacturer") bits after much delay, debate, and discussion across the Internet. The release to manufacturer build contains the final bits which will ultimately be sent to MSDN customers, TechNet subscribers, Volume License Holders, and the general public. Before that, it is sent to OEMs. ("original equipment manufacturers").
Microsoft has confirmed the RTM build number is 7601.17514.win7sp1_rtm.101119-1850 and we now have the highest level of certainty that these files are Windows 7 Service Pack 1 "Release to Manufacturer" (RTM), as we previously announced on January 14th. Microsoft TechNet Russia initially identified this build as the release to manufacturer version on January 14, 2011, but issued a warning that it had not yet been released to OEM partners.
