Windows is slowly losing configuration. From the very first versions you had complete control over fonts, colours, and sizes of UI elements, then starting with Win8 they removed that, and now in Win10 it's very hard to change something like the font for icons and the (horribly low contrast) taskbar button highlight colour.
It's still possible to force (most of) it to the good old MS Sans Serif and with no antialiasing, the way I like it, but it's getting harder with each new version.
