    information   Information
    Processor frequency specifies the operating frequency of the CPU's core(s) in MHz. The higher the frequency is for a CPU, the faster the processor is.

    You can specify the approximate maximum frequency (in MHz) of your processor from within Windows 10 to limit the frequency if needed. For example, to save energy or the CPU is running too hot at a higher frequency. By default, the maximum processor frequency is set to 0 for unlimited allowing the processor to run as high as what is capable of.

    This tutorial will show you how to change the maximum processor frequency setting in Power Options to what you want in Windows 10.
    Note   Note
    Any changes to the maximum processor frequency setting will affect all users on the PC that use the same power plan.

    MS is slowly removing features that were in the CP. One day it will all be gone.

    Thank you for letting me know guys. Tutorial updated.

    You can add this setting back if wanted, but there's really no need to change it unless you wanted to limit the CPU max frequency.
