    Why is Win10 showing 100% CPU in task manager?


    I recently installed Windows 10 LTSC 64bit 2019 and I've noticed every time I open task manager, especially for the first time, it shows as 100% for CPU and then drops to its expected level a few seconds after. I can literally boot up my PC with nothing really loading in the background and it'd say 100% CPU and then drop to <10% within a few seconds after that, and I've never understood why. Is there an explanation?

    CPU @ 100% in Task Manager.. but in error


    Sailindawg, did Resource Monitor show some silly high % use, in the millions/billions? Does the 'Details' tab in Task Manager show 'System Idle Process' normal? It does sound like you have the same issue, I've still not fixed it. You might be lucky and a BIOS update works for you as it has others, I'm stuck on the B2 stepping which means I can't upgrade the BIOS *Sad

    MrPumpkin, what process does task manager say is using the most CPU usage?

    Why does task manager say that CPU is 100%?

    No tasks are running, yet why does task manager say that CPU is 100%?
