Windows Vista build 3790.1232 is the first "Longhorn" build compiled after the development reset. Basically, it is a rebranded Windows Server 2003 SP1 beta. There is no evidence that this is a "Longhorn" build except for references in the End-User License Agreement. It was described by Grabberslasher on his UX.Unleaked blog on 2008-05-02. Unlike other post-reset builds, this build does not use BOOTMGR and can still boot without ACPI.

This build is not functionally a Longhorn build, but since it has the Longhorn EULA (End User License Agreement), it was still distributed as a Longhorn build and was intended to be tested as such.
