Since about 1 week ago, the minimum requirement is Windows 8.1. Hardware
requirements were also recently upgraded. A CPU from 2007 onwards should
be fine:

AFAIK nothing changed for MinGW-w64. I don't know about their planning,
though.

See above. Please note that Mingw-w64 alone is useless, you need to
configure your toolchain to use it. MSYS2 provides toolchains ready to
use. Plus, requirements such as libwinpthreads, which are also
maintained by Mingw-w64, might have their own requirements (AFAIK
nothing changed yet.)

I would say that for using an MSYS2-based build of Emacs you need
Windows 8.1 at the least. A more future-proof statement is to recommend
looking up that information on the MSYS2 web page.
