From inside the bowels of Micro$oft (or at least out of MSDN) comes an intriguing look at the massive, multiheaded monster that is the creation of Windows Vista.
An interesting question, however, is whether or not Windows Vista ever had a chance to ship on time to begin with. Is Vista merely uncontrolled? Or is it fundamentally uncontrollable? There is a critical difference.
Spend some time reading the comments as well. Are all lines of code equal, or are some more equal than others?
