So I was going to argue that ARM on Windows makes little sense, but then I realized you have this Snapdragon that runs Windows (I forgot this existed). I'm still not a fan of Windows, but yes it makes sense to have support for it. I'll schedule some time for this and I'll let you know so that you can test it on your machine 👍
