Putting easter eggs into an operating system is not a good idea for a number of reasons. But, more importantly, I don't want you to get the impression that Microsoft is a bad place to work because easter eggs in Windows is frowned upon. Microsoft is a great place to work. We were allowed (encouraged, really) to create Channel 9, after all. Consider how other large corporations would react to the notion of a Channel 9 type of web community...
I think easter eggs are dangerous. Consider if a backdoor entry point was disguised as a harmless little easter egg...
No, not in Windows. Can't have that.
