Resource usage after installation. Turned off all cortana stuff. No apps running. Compared to windows 8.1 there are more processes, 50% more threads and handles, disk space usage is about the same, but with 40 000 more files in the windows directory.

Every setting has one more layer of ui on it, but deep down, the same dialogs come up, with the same unusable interface.

Smaller window borders are nice. New alt+tab is a bit nicer. Window close red X is a bit easier to hit.

Setup is awful like always. Stops midway for a question, then you have to wait for an other 10 minutes till completion
