In this video I begin our investigation into the development of Windows XP (complete with added dog barking) with build number 5111 of an entirely separate but nevertheless seminal Windows project: Neptune.

Designed to be the first Windows consumer operating system to be based on NT, Neptune introduced many new features in Windows which would later make their official appearance in XP (NT 5.1) and, in some cases, even later in Vista/7/8 (NT 6.x). These features include:

-Welcome screen on boot-up
-Integrated Windows firewall
-Automatic updates (also present in Windows 2000, but it’s unclear whether this feature was ported from 2000 to Neptune, or vice versa)
-UIs for task-centred operations (Neptune’s “Activity Centers” have many features which later appeared as part of other inclusive Windows software such as Windows Media Player, Windows Media Center and Windows Explorer itself)

In addition, features from Neptune which were not present in XP but have appeared in later versions of Windows (NT 6.x) include:

-UI for game-centered operations (Neptune’s “Game” Activity Center has similar features to the game center present in Vista and 7)
-“Fast boot up” option (Neptune’s “fast boot up” capability seeks to perform a similar function to that now present in Windows 8)

Virtual machine hardware specifications:
-256MB RAM
-Intel Core 2 Quad processor @ 2.40GHz
-Virtualisation by VirtualBox 4.1.12
