Unexpectedly I have something positive to say about Windows (10): The alt-tab dialog with the preview is actually good. Better than macOS und better than half the ones in Linux window managers/desktop environments.
Win-1/2/3 for pinned apps works but it's also broken in that if you e.g. close your main browser window (not the second one opened) and then reopen it, they're switched and you can't change the order. Yeah, you could accidentally close the 2nd and restore it, but most applications don't have this functionality, only browsers.
