Neptune reference
One file, namely, with the version number 5.50.5067.1 and product name Microsoft(R) Neptune (TM) Operating System was found in this Millennium build, but it is unknown whether this Neptune build was ever compiled.

Some speculate it would probably be part of the Milestone 1 stage. Judging by the file dates, it would have been compiled before 20 September 1999.
