TechNet/MSDN/Volume Licenses: February 16, 2011 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.Īlthough the files have already leaked, we now have dates for the official release timetable: Microsoft has confirmed the RTM build number is 7sp1_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. Windows Server 2008 R2 SP1 and Windows 7 SP1 was released to manufacturers ("RTM") on February 9, 2011. 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. 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 build had leaked to the Internet around January 14th. Windows 7 Service Pack 1 (SP1), or KB976932, was confirmed as being pre-released to OEM manufacturers on February 9, 2011.
