Windows Neptune build 5000

There is no proof this build ever existed at all. Screenshots of this build exist, but they are known to be fake. These screenshots originated from a user called "A.Nonymous", later revealed to be a pseudonym used by OBattler, and were posted on BetaArchive. It was claimed that it was compiled on June 3, 1999.
