Windows 10 has its own UI problems. It is very chatty, possibly even more than Vista, there is an almost permanent flow of notifications on the bottom right corner of the screen. When searching for something in the start menu the result is completely unpredictable, and searching for "control panel", "mmc" or "adapters" usually yields nothing, but sometimes it does. The permanently evolving two control panels makes that even when you learn where a setting is, it can move to another panel within 6 months. There are many rough edges. Like you launch a remote desktop connection, you get a grey window asking for credentials, the login is not selected by default and no keyboard shortcut allows you to select the login box, you must use the mouse. I really question whether Microsoft engineers even use their own OS.
