Windows Vista build 3790.1232 is one of the first builds of Windows Vista compiled after the development reset, and the first to be built by the new winmain build lab. It is essentially a recompile of a contemporary Windows Server 2003 Service Pack 1 build with the same number, and therefore not functionally a Longhorn build. However, as it was compiled from a branch that was only introduced within post-reset Longhorn and was distributed with the Longhorn EULA, it is still usually considered as one. The build was first shown by Grabberslasher on his UX.Unleaked blog on 2 May 2008. The Professional SKU variant of this build was uploaded onto the BetaArchive FTP server on 14 August 2011, while the unmodified Professional copy and Home Edition versions of this build was shared by Grabberslasher in the second set of his 33 Longhorn/Vista builds on 25 January 2020.
