    System running high CPU usage after a Windows update failure in early January


    Windows update KB5034441 error 0x80070643 - I'm not quite sure but I believe this was the one. "System" is running high CPU usage above 20% constantly since then. My PC was Windows 10 by then and I upgraded it to Windows 11 two weeks later but that doesn't fix the problem. What cause it and how do I fix it?

    :)
