I think this seems true only because of Microsoft. I cannot recall any other major OS spending so much effort on backward compatibility.

The king of backward compatibility is probably IBM. AFAIK, their mainframe operating systems can run unchanged software from before MS-DOS was born.
- wilsonnb 9y agoThat's true. You can supposedly run a program assembled or compiled in the 60's on a z14 that you buy today. Seeing as most of IBM's largest customers are banks and other places that have no interest in rewriting battle tested software, it's probably the reason that their mainframe department is still alive.
