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


    information   Information
    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.

    Is there any way to change the min/max values from the registry or through a batch script or something? When I play games my laptop gets hot, so I switch the max value to 94% just to disable the turbo boost, which in turn lowers my max cpu temp from 100 degrees Celsius to something more acceptable like 70-80, and after I'm done playing I switch back the max cpu power to 100% again. Needless to say this process is very boring, and if I could do all those commands with a double click it'd be awesome.

    Hello Legjendat,

    As a workaround, you could add the context menu in the tutorial below to be able to quickly change power plans on demand. This way you could set two power plans each how you like for the processor state, and use the context menu to toggle between them.

    Hmm, that's a very good solution as well so Thank You for the fast response, but while I was googling, I found exactly what I was looking for. A tutorial to change the power through a batch file. If you want, you can add it as part of this or some other tutorial.

    You create a batch file, and add the following commands.

    The commands are simple, and you just change the values at the end of each row.

    powercfg -setacvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCTHROTTLEMIN 5
    powercfg -setdcvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCTHROTTLEMIN 5
    powercfg -setacvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCTHROTTLEMAX 94
    powercfg -setdcvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCTHROTTLEMAX 94
    powercfg.exe -setactive SCHEME_CURRENT
    setacvalueindex is for when the power cord is connected while setdcvalueindex is for when you're not connected to a power plug. I just created two batch files, one for gaming with the stats above and one for full power with max values set at 100, nice and easy

    Hello Martin, thanks so much for this great info. I'm using the TrekStor Wintron 7.0 Tablet with Windows 10, and these processor state options were missing. I don't know if these were removed intentionally, but nevertheless it has worked. During low demanding tasks the processor liked to be at full clock speed very often. Now it's finally not the case anymore, and as the average battery runtime of this device are 2 hours, this is very helpful.

    And I'm a bit confused about this sentence:

    Only when virtualization is disabled in BIOS/UEFI will Minimum processor state and Maximum processor state be available in your Power Options.
    On my main computer this option is enabled, and processor states are available. During tests with Windows 8.1 and 10, it is the case too. The tablet also supports virtualization, but I don't know if it was missing because of that. It has luckily still worked anyway

    By the way I have to say, I have seen your tips and posts previously many times through my Google searches. And it's always so helpful. Thank you again!

    Hmm... This did not seem to work for me.

    I downloaded and used the files as instructed, however the options are still not present for me. The strangest part about this is that I incorrectly set them earlier today, and I need to set them back, but now they're gone... I did tinker around in the BIOS in between setting them, but I'm not exactly sure what I hit there that may have affected the settings... I know about the virtualization option having something to do with it, but I've deactivated it so that shouldn't be hiding the options. The only thing I can think is that disabling Intel Speedstep may be the culprit, but I really don't want to have to turn that crap back on, even just to see if that affects the options. What is left that could still be hiding them?

    Hello theataripunk, and welcome to Eight Forums.

    As a test, enable Intel Speedstep in BIOS, and see if the settings are back in Power Options afterwards.
