    System taking too much cpu


    My laptop is quite new with the following specs

    Intel(R) Core(TM) i7-4500U CPU @ 1.80GHz
    8Gb Ram
    1Tb harddrive

    but sometime system.exe takes up as much as 80% of the CPU. and it does causes the mouse pointer to stutter/ hangs. Even-though Power plan is set as "High performance"

    Update drivers to everything, from manufacturers' sites. Uninstall any 3rd party security and use Defender/WF instead, to test.

    Ok, then use the removal tool for it to ensure all remnants are removed as well.
