    taskhostw.exe causing 99% CPU usage


    Been having this issue for a few days now, as soon as I turn on my pc there is a processId which is always different showing 99% cpu usage in a perfmon /report.

    • I have run several virus / malware scans and got rid of any seen issues.
    • Process explorer and task manager do not show a process that is using this much CPU.
    • Any CPU graphs do not show high cpu.

    Issue is causing my PC to run super slowly.


    Thanks

    :)

    CPU at 99%

    Hello,

    To better assist you with your concern, we would like to ask you a few questions:

    • When you start your computer, is the CPU usage already at 99%?
    • Do you have programs on your startup items?

    Regards.
