I found this article on Gizmodo this morning that clearly shows that Cylons (from the TV show Battlestar Galactica) are running Windows XP, and possibly Windows XP Embedded on their Base Ships!

Of course the Cylons are smart enough to realize that using Windows XP Embedded gives them a reduced operating system footprint (through componentization), application and driver compatibility (which is why humanoid Cylons are so hard to spot!), and of course embedded specific technologies such as Message Box Interception (you don't want those annoying operating system or application message boxes appearing!), and Hibernate Once Resume (or should that be "regenerate") many (HORM) for fast boot times.
