Yeah, the entire MS business depends on backward compatibility. Check
Raymond Chen's book 'The Old New Thing' for really fun stories of the great
lengths MS developers go to maintain such compatibility.
Also Check the mentioned book 'extras' online chapters on the publisher's
page, where the author maintains backward compatibility for Win3.1 games in
his youth days. At the time where hardware protection wasn't used by Windows
and the code Windows was trying to be compatible to was doing amazingly
silly stuff with the x86 processors and PC architecture nuances (GDT, IDT,
PIT, etcetera).
