How to Add or Remove "Minimum processor state" and "Maximum processor state" in Power Options in Windows

The Minimum processor state is the minimum performance percentage your CPU will automatically decrease to save energy and battery life when there is little CPU demand by the system. You would want to keep this percentage the same or lower than the Maximum processor state setting.

The Maximum processor state is the maximum percentage performance your CPU will automatically increase to save energy and battery life when CPU demand increases. You would want to keep this percentage the same or higher than the Minimum processor state setting.


This tutorial will show you how to add or remove the "Minimum processor state" and "Maximum processor state" setting under Processor power management in Power Options for all users in Vista, Windows 7, and Windows 8.

You must be signed in as an administrator to be able to do the steps in this tutorial.

Note   Note
This could be handy if you wanted to set this how you wanted, then remove the setting to prevent other users from being able to change it in Power Options.


If you enable virtualization in your BIOS or UEFI settings like below, then the Minimum processor state and Maximum processor state power options will not be available, even if you set them to be added.

Only when virtualization is disabled in BIOS/UEFI will Minimum processor state and Maximum processor state be available in your Power Options.

Hi Shawn. I created an account just to say THANK YOU for this tutorial. I was going crazy not being able to set minimum power to 100% when charging. It was reset to 5% by some idiot OS upgrade which also wiped my High Performance plan.

THANK YOU.
