MacOS is at a standstill in terms of usability, but I feel that windows 10 has gone back.

Microsoft has chosen to focus on enterprise. This is probably the right move for their culture and the future of the company, but the remainder of their consumer products seem to be turning into an ad-supported model heavily focused on legacy support.

Windows may have a new coat of paint, but the underlying OS just gets more buried under more and more simplified UIs which ironically make its harder to use.

This is really desktop linux's time to shine, but it's usability is still sporadic.
