I have to use Win10 on some machines at work and just find it so much less refined. The latest Edge full-screen modal is another example of Microsoft's UX misses. The "are you sure, really sure, OK fine" change the default browser is evidence that they don't put the user first. No, I'll keep my Mac thank you.
Isn't it weird that so many error and configuration screens still look like Windows 3.1, complete with that turn-of-the-century bold pixellated font? It always catches me off guard because it's so jarring compared to everything else in the UI.
