Windows Me build 2525

Windows Me build 2525 is the official Release Candidate 0 build of Windows Me. It is notable for being the first Windows Me build to include an introduction video. Windows NetMeeting has been downgraded from version 3.1 to 3.01 SP2 for unknown reasons.

Neptune reference
A file named, with the version number 5.50.5117.1 was found in this Windows Me build, but it is unknown whether this Neptune build ever existed.

Some speculate this would've been a Milestone 2 build. It would've been compiled someday after 11 December 1999, meaning it would be one of the last Neptune builds before the Neptune project was canceled in January 2000.
