    explorer.exe high cpu usage - crypto mining suspect


    Hello, I'm running windows 11 latest update. The last night I notice by a "rainmeter skin" that check cpu and top process usage that my cpu was using 100% on 2 cores of 6 from my i5 9400f when system is idle. As open task manager the explorer.exe usage go down "normal" so 1-4% in idle.Also, I saw in the running process two explorer.exe, when open the taskmanager "the one suspected" remain still there, but with no % usage, so I tried to kill that one and...guess... explorer doesn't restart, as usual when kill it, and "the issue" goes away...so closing again task manager cpu, and explor

    :)

  2. Windows Explorer high CPU Usage in Windows 10

    Hi Andrew,

    Usually, too many background processes can boost your CPU usage. Since you already disabled the apps that are not necessary on startup,
    we suggest checking the applications running once you have successfully boot Windows 10. To do this, simply follow the steps below:

    • Click on the Start button and type Task Manager on the search box.
    • On the Task Manager window, you should see the programs running.
    • Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

    From there, you should see what applications are running on high CPU usage. You can also
    restart the Windows Management Instrumentation service and see if your CPU performance will improve. Follow the instructions below to restart the service:

    • Click on the Start button and type Services.
    • Scroll down the list and look for Windows Management Instrumentation.
    • Right click on it and select Restart.

    Should you have further questions, please let us know.

  3. Windows Explorer high CPU Usage in Windows 10

    To further troubleshoot the issue, we suggest checking the Task Manager again to see what are the
    applications that have high CPU usage. To do this, follow the same steps you did from the previous reply:

    • Click on the Start button and type Task Manager on the search box.
    • On the Task Manager window, you should see the programs running.
    • Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

    However, based on your response above, it seems that you may need to create a new user account again and just install your apps manually instead of copying them as your
    previous user account might be corrupted.

    Once your done with the steps, please let us know how it goes.

    Windows Explorer high CPU usage as Apps or Background Process...

    3May2018...

    Running Windows10 Home Ver 1709 latest OS Build on

    Intel Core i5 CPU @ 3.8GHz.

    Recently Windows Explorer has been running at high CPU usage 45% to 50%

    Even when I am not using File Explorer - Windows Explorer runs as a Background Process as same high CPU usage...

    First when will Microsoft stick to the new name File Explorer - instead of showing Windows Explorer as the app in the Task Manager...confusing :-(

    Two - I saw someone else with the same problem and a ridiculous multi step cumbersome solution of creating another account (where Windows Explorer did not have high CPU) and then a painful exercise of trying to migrate all applications and files from one
    account to the other.

    Apparently the original user account may have had a corruption....

    Are there any simpler explanations out there on how to fix run away Windows(File) Explorer???
