>Windows 8 and beyond, however, have been less so.
While they didn't stick too well to the old paradigm in detail, they introduced ribbons in Windows 8 Explorer, which are keyboard-friendly and very "vimperator-alike", using modal hints for commands (press Alt in Explorer to see how it's different), and support the quick toolbar. That's a massive improvement on itself, compared to the old accelerators. There were also many other keyboard-friendly improvements like the basic window tiling and separate desktops, ability to cycle tray icons, almost every OS setting being accessible from the console instead of GUI, etc. I'd say Windows 8 was the first Windows version somewhat usable without a mouse, in Windows 10 they improved on it (and made a huge step back with WPF applications).
