    Wrong CPU cores display in Task Manager


    Hi All,


    Hope you guys are doing good. there is a strange problem with my windows 10, that i can not see correct core information and i assume therefore my Windows is running slow.

    My Device manager shows total 16 cores in CPU section, however in Task manager i only see 4 vCPUs.

    I tried almost every solution but still no luck.

    - I Tried msconfig and increase the CPU Cores but it didn't help even after restart.

    - I updated Windows , still no luck.


    Any help will be highly appreciated.

    wrong CPU cores in Task Manager

    i upgraded my CPU from i7-7820x 8core/16Threads to i9 14cores/28threads, the Bios shows all 14cores, Device manager shows all 28threads, in the task manager the model of the processor is correct, but still shows 8cores/16threads, i have reboothed the cpu
    twice, still shows the old processor values

    task manager displays wrong cpu speed/utilization

    Hi Jimmy,

    Thank you for posting your query in Microsoft Community.

    I understand your concern and will be glad to help you.

    Task Manager displays the programs, processes, and services that are currently running on your computer.

    On the CPU section of the Performance tab, the actual CPU is now specifically identified in detail with the brand, the model number, the speed, as well as the number of sockets, cores, and logical processors.

    Other third party performance monitor specifies the utilization and speed of the processor using different algorithms which differs from Windows Task Manager computations.

    In addition, different algorithms are used to measure performance. For example, the algorithm used by Intel in its branded maximum speed is different than the algorithm used by Windows Task Manager to directly measure the speed of the CPU. You can use other
    processor utilities, such as the Intel Processor Identification Utility or CPU-Z, for additional processor speed measurements.

    Keep us posted if you face any issues on Windows in future. We will be glad to help you.

    Thank you.
