Project Zephyrium

Zephyrium was the codename for an alternate branch of Windows that was originally going to be marketed for high-end workstation machines. The project was cancelled due to complications with certain applications that were previously compatible with Windows XP. According to bits and snippets of source code, it was supposed to be released between 2005 and 2008. Because the project was open-source (link is now dead), many builds of the operating system were archived, but some were later lost due to hard disk corruption.
