Whistler, Microsoft's next major consumer operating system, aka Windows 2001, has been leaked onto the Net - again. It's a month since it last happened, and according to the guys over at ActiveWin, the latest release is a more up-to-date version of the OS. For its part, Microsoft claimed it doesn't yet know whether that's the case, but that it's continuing its investigation into the previous leak. The latest leaked Whistler internal release is Build 2223, says ActiveWin. The previous leak was Build 2211.1. "This [release shows] that the operating is as expected moving ahead with the beginnings (Very early beginnings) of a newer Graphic User Interface and many UI enhancements are coming into the fray," says ActiveWin. ® Related Stories Allchin admits Win2001 code leak after Web slagfest MS code leak 'ships' Win 2001 a year early
