  • Hi,

    Did you install some third party software?

    Check for Windows update and install the latest update packages.

    Try to update your Windows Defender and perform a full scan. Then disable antivirus and firewall temporary and perform a clean boot.

    If the issue don’t occur in a clean boot environment, please uninstall your third party software by dichotomy to check the issue.

    Or we could use Windows performance toolkit to monitor the detailed process and memory information of disk performance.

    This tool is consists of two independent tools: Windows Performance Recorder (is used for recording process) and Windows Performance Analyzer (is used for analyses).

    If it is difficult to analyze the file, please upload the file to OneDrive and post a link here.

    Best regards,

  • Of course, as someone who works for Microsoft, you blame "third-party" software, as if "third-party" were a dirty word. I know you're incredulous that anyone would use software that Microsoft doesn't make or control. News alert: Microsoft doesn't make every kind of software that someone might find useful.

    Is this an ad hominum attack? You bet. You're answer doesn't address the real issue, that part of Windows is malfunctioning. You are so blind, don't even consider it as a possibility.

    Will there ever be a real answer to this question? Don't hold your breath.

  • You might want to check your windows media player network sharing service.  It runs whether WMP is active or not and it's a memory and CPU hog.

  • After dealing with this for quite some time, I finally had enough this morning and went searching and found this post.  Sure enough, WMP was the issue as I had a music location to another networked machine in my house!  Disk util went from solid 100% down to occasional 9-20%.  I really appreciate you posting this stockwellpg.  You made my week and then some... seriously.  ;-)
