Microsoft loves using code names. If you can remember what the monikers Longhorn, Orcas, Whidbey, Whistler, Janus, Hydra, Bobcat, and Thunder represented within Microsoft at one time, then my hat’s off to you. If that’s the case and you are a Microsoft code name fanatic, then you also probably know that the successor to Windows Vista is code-named Blackcomb, or so it was. The next, next generation Windows operating system is now being called Vienna, as confirmed by Robert Scoble via Channel 9.
