Windows Neptune build 5116

A total of 8 files with version number 5.50.5116.1 can be found from Windows Millennium build 2452 to build 2495, 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 1999-12-11, meaning it would be one of the last Neptune builds before the Neptune project was canceled in 2000-01.
