What can cause Explorer to consume >50% CPU for extended periods?
Well, the subject says it already. I again and again witness that my tablet (Surface Pro 7) gets very hot, even though I am only browsing or reading a PDF. When I then check the CPU-load with TaskManager I regularly "catch" Explorer in-flagrante consuming 30-50% CPU and not seldom there are several instances doing that, which then easily adds up to typically 80-100% CPU load. Funny enough that activity typically seems to stop or at least be reduced as soon as I have TaskManager open for while and interestingly I never witnessed it going beserk when I kept TaskManager open on-screen.
What is this beast doing in the background? My expectation would be that Explorer sits idle doing nothing when I don't use it but apparently it decides to start some background "business" when not used for while. Is it indexing something or what?
BTW: That's not a new effect - it behaves that way at least since Windows 7 already - if not longer. But on a battery-based device this is *really* annoying! Can one somehow stop it from doing whatever it *is* doing here?
