Vista, 8, and 8.1 were the worst of the past 10 years. I've used 7, so I'm quite familiar with it (I've extensively used every MS OS since 95 and NT). !0 is distinctly its own, but it takes a windows 7 desktop and adapts some Windows 8 elements (from the perspective of what you see, not what is actually happening underneath). Control Panel is replaced by Settings, but the device manager and other elements are still there, just mainly presented differently. In some ways it's a much more intuitive approach; but learning your way around takes a little time.
