I have this issue on my older laptops with Windows 10 that I rarely use. The culprit is some Windows Store "optimization" process (wsappx). It'll run for days at 100% if you don't boot Windows for long enough. I hear the exact same from friends. It's clearly a blatant bug that's been going on for years now, and Microsoft doesn't give a shit.
