IMHO, "it just works" has never applied to Windows and probably never will. The arcane UX changes for the sake of change, arbitrary removal/renaming of features/actions/applications...
My favorite random "made it worse" change in Windows 10 is that with multiple monitors, your cursor gets stuck at the top/bottom corners between the two monitors, causing me to frequently click the Close "X" on the program/window I have open, because I was actually trying to click something on the monitor to the right. It doesn't matter if you were moving the mouse cursor very quickly. There's no registry flag for this, so the only known workaround is to run some 3rd-party application 24/7 which will take over the cursor position to nudge it over if you hit the edge.
