I, for one, hate how disregarded the system makes me feel. The experience is much closer to a remotely managed computer, like the workstation I have at my day job, than to using a personal computer.

This applies to how the updates are handled, the telemetry stuff in general, the way the Control Panel and other settings are arranged, and so on. It's hard to pinpoint one specific thing, because the whole system is steered in this direction.
