Win10 is a good OS. Sometimes it can act junky, but it scales to modern hardware very well. My largest gripe is the continuation of 2 control panels and the orginization of what is under each. That's a mess and comes off as low rent Linux distro like. But otherwise just accept your software-as-a-service future. Nothing you can do about it anyway.
The 2 control panels are a bummer, but I feel like they exist to satisfy where they want to go with the modern simplified one, and the classic one for the users that didn't like where 8 went with the Tablet-focused start menu.
I do think that will improve, and Ballmer being gone has probably helped the most.
