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