If I run a program written for an earlier version of a system under a new version then I expect that the program works. That means upward compatibility. Yesterday I downloaded some Windows utilities from an anonymous ftp. I tried to run them under my Windows 3.1. They messaged that they were written for Windows 3.0, and they might cause unexpected errors under Windows 3.1. And they did! That means that Microsoft do not obey the expected rules of upward compatibility.
