How to Add or Remove 'Maximum processor frequency' in Windows 10 & 11

Maximum processor frequency specifies the operating frequency of your CPU's core. The maximum processor frequency option is hidden and set to 0 by default, which means your processor runs as fast as allowed. Advanced users can slow down the processor if your computer is running hot or consuming too much power.

Once added you will see the option Plugged in, and laptop users will also have On battery.



To edit the Maximum frequency, type in, and click on Edit power plan, and then click on Change advanced power settings.

Here's a before and after:
