    CPU usage unexplained high


    Yesterday updated system via Windows update , just normal security monthly , and cumulative updates , and today turned system on . Task manager has unexpectedly showing cpu useage at very high levels 100%. Normally CPU usage at 5% with
    No more than normal programs opened .

    Ran full scan with Defender and full Scan with Malwarebytes Pro . Neither showed positive.
    Noted as per attatched snip , 6 unicode exe running , ended 5 of these running which dropped cpu useage down to 15%.
    What is updater exe unicode. and have i created issue by ending 5 of these running simaltaneously .

    :)

    high cpu usage

    After downloading windows 10, anytime I run any programs, I get high CPU usage. It does not matter whether it is google chrome, task manager, playing games, whatever. Anything seems to spike the CPU usage. I have already run malwarbytes and my antivirus
    programs and find no viruses. Any suggestions? Thanks.

    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.
