Description

The OS itself is based on Longhorn build 4074, which was a Milestone 7 build of Windows Vista released in April 2004, before the development reset. The OS is mostly stock except for some integrations, icon replacements, and themes, and certain programs are taken from other Longhorn builds to make it more "stable".
