This is basically the story of each of the last few generations of Windows - the core of the operating system has gotten considerably more stable and better at each iteration, only to be stymied by the UX changes which are undesired and generate considerable hate.<p>Worst of all is when those UX changes are spotty and inconsistent.  Windows 10 is a fantastic upgrade, so far as the core operating system goes.  But the UI is a complete trainwreck lava-layer, particularly in the control panel and settings dialogs.  Bits of it are essentially unchanged from Window 2000, other parts are Vista-era, others from the Windows 7 generation, yet other in the Metro Windows 8 or whatever they are calling the Windows 10 style.  Some things can only be managed through the older UI, some only through the new UI, some in both, and some in both, but with subtle and non-obvious differences.
