At this point I'm not sure that a desktop OS with this wide hardware compatibility and backwards compatibility can be written any better than Windows 10. The thing is, if you are an experienced user with willingness to search for solutions, you can fix most of the problems. Disable updates completely, disable cortana, stop 99% of the telemetry, use alternative utilities instead of the built-in ones, fix security issu…
The fixes you've listed get overturned by Microsoft. Just because you can hack around windows to make it temporarily do the things you want, doesn't mean it's a resolved problem. Microsoft only does this because they've been able to reduce consumer expectations. Being a part of that means the next version will be worse.
Of course this state of things is far from ideal, and it's not easily available for everyday users. But I think an open source desktop OS could have never achieved the things that Windows is respected for.
