My understanding of notepad.exe is that it's a very-few-loc wrapper around a fundamental windows UI element. That's why it can be fun to see that there are bugs in its implementation. It reminds me of this joke: Every program has at least one bug and can be shortened by at least one instruction — from which, by induction, every program can be reduced to one instruction which doesn't work.
