Latest versions of software for specific versions of Windows

This page is a work-in-progress. Stuff might change, and probably will.

Quick legend:

bold means “this was the current version when last checked, but any new version might stop working”
italics means “last version unconfirmed, but this version works”
? just means I haven't checked yet.
… means either of those:
- this piece of software is way older than the OS, so probably the last version works
- somehow this OS still has a long way to die, so why bother
- means it's incompatible anyway
