    CPU utilization >100%

    I recently upgraded from Windows 8.1 to 10, and discovered a weird problem when opening task manager where CPU utilization was always at 100%. I did a clean install of Windows 10 to make sure it wasn't application specific, but still the same problem.

    This problem is very strange because utilization doesn't seem to be tied to a specific process- it just always seems to add up to 100%. Resource monitor actually shows CPU Usage to be in the million%, which is definitely wrong. No performance degradation,
    CPU temps are very normal, and even third-party programs such as Speedfan and CoreTemp are reporting negligible CPU usage (1%-2% idle).

    I have tried disabling all startup applications, doing sfc /scannow, viewing reliability history, and restarting multiple times. No luck

    CPU utilization in desktop

    My CPU is 2% in idle, but my CPU utilization in 100% even on idle. Is it normal to have a high CPU utilization even if there are no apps running?

    CPU:2%

    CPU utilization: 100%

    Thanks, appreciate it.

    CPU Utilization

    What is CPU Utilization?

    Mine is 100%, should I worry?

    Don't know the appropriate product, pls move if this question is in the wrong product.. thanks.

    EDIT: MY CPU is normally 1-15%, I check task manager, click Performance.

    CPU= 15%

    CPU utilization= 100%
