If I could have total control of the OS I would undo all of that bullshit. An OS shouldnt feel like it was made by Google full of ads nobody wants or is asking for. Also the insane telemetry considering telemetry left Microsoft with Windows 8 one of the more hated versions after Windows Millenium Me which was a buggy piece of trash.
Microsoft has always been full of marketing shitfucks. Like when they rebranded Lync to Skype just because and dumped a whole communication campaign on their paying customers just for one marketing goon's KPI.
But they get away with it. Nobody buys Microsoft because they're good. It's because they have so many fingers in the pie that you can't do without them. They know it and make their products just good enough to not be dropped in favour of something much better.
