(Checks code...) Looks like the experimental Windows native AIO code
we have today, namely io_method=windows_iocp, only needs Vista.
That's for GetQueueCompletionStatusEx() (before that you had to call
GetQueuedCompletionStatus() in a loop to read multiple IO completion
events from an IOCP), and otherwise it's all just ancient Windows
"overlapped" stuff.  Not sure if we'll propose that io_method, or skip
directly to the new io_uring-style API that appeared in Win 11 (not
yet tried), or propose both as long as Win 10 is around, or ... I
dunno.
