Windows 7 build 7601.17514 is the official RTM build of Windows 7 Service Pack 1 that was released to manufacturing on 9 February 2011 with the build being released to MSDN and TechNet subscribers as well as Volume License customers a week later on 16 February 2011. On 22 February 2011, it became generally available for download via Windows Update and the Microsoft Download Center alongside its server counterpart.
It is the last Service Pack to be released by Microsoft before they were dropped starting with the release of Windows 8. It is also the last build to support processors without the SSE instruction set (prior to update KB4088875 in 2018), as SSE was enforced starting with Windows 8 build 7700; therefore making it the highest possible build to install and run on emulators like 86Box, as SSE-compatible CPUs are currently not supported on those programs yet.
