Microsoft Cairo build 1175.1 is a late build of Microsoft Cairo, based on the core of Windows NT 4.0 build 1175.1. This build was uploaded to BetaArchive by The Distractor on 17 March 2017. Due to having IDW, DUMP and MSTOOLS folders in the I386 directory of the installation media as well as compiler-output file CHKFILE.BLD listing checksums for each file, this build came directly from MS build servers at the time. The build notably integrates Cairo Object File System support into the build, alongside some updated components for Cairo, such as domain support and an updated login screen.
CHKFILE.BLD also proves Cairo components were built separately (to a CAIRO folder) and then copied over the base build, something that happened again with Neptune four years later.
