How to Add or Remove "Maximum processor frequency" from Power Options in Windows 10


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 add or remove the Maximum processor frequency setting under Processor power management in Power Options for all users in Windows 10.
