Easter Egg for Windows

What is an Easter Egg? 

Easter eggs are messages, videos, graphics, sound effects, or changes in program funtions that sometimes occur in a software program in response to save files or mouse clicks, as a joke or to display program credits, well in my opinion those egg are parts of strategies for sell more software because when users interact with them can understand that is a extra material.

there are  many popular eggs found!!!! for examples
