Ask HN: I'd like to request Microsoft open source Windows XP

I guess I have two thoughts that spring to mind regarding this;

A) why?

B) they can't. Because XP is not like some notepad app someone wrote. Rather it is a collection of software, a lot of it owned by not-microsoft and licensed to them. And that's before we talk about the security implications to existing systems still running XP.

Thirdly, what possible benefit could they get for doing this? I can see plenty of down-sides, including some very large potential economic and legal downsides. But I can't think of an upside.

ReactOS already exists and targets the API level as XP. You can even install the same Luna theme that XP used to make it look like XP.

Windows is continuously developed, and many parts of it changed very little between XP and 11. Not going to happen.
