As part of anti-trust deal, MS had to document all APIs and file formats, and there was a massive internal effort to do so. Basically it’s not allowed to call non-public APIs from one MS product to another. On top of that there was massive security push when entire Windows division stopped working on new version and concentrated on security of XP for many months. After these traumas there was no way Easter eggs would survive.
