I have to use Windows 10 at work. The flat white UI makes navigating File Explorer excruciating. Borders between panels are nearly invisible, clicking on them means fine mouse control to juuuust hit that one or two pixel trigger point, functions are hidden in ribbon panels, ... the beat goes on. In exchange I get absolutely nothing in terms of capability or performance.
