Default Values of Power Setting GUIDs?

友谅 强 21 Reputation points


I refer to a performance tuning article in Microsoft Learn website with my Windows Server 2019. This article mentions some strategies for processor performance and power consumption settings, such as:

The processor performance increase and decrease thresholds and policies, regarding this policy setting, can be set by the PERFINCTHRESHOLD and PERFDECTHRESHOLD parameters through the powercfg tool.

Now I have a doubt. After I set up my system with the following command, I found that the performance of my program is not running very well:
Powercfg.exe -setacvalueindex scheme_current sub_processor PERFINCTHRESHOLD 10

Now I want to restore the original default settings, but I don't know what is the default value of the PERFINCTHRESHOLD parameter?

  1. How can I get the default value of PERFINCTHRESHOLD?
  2. How to restore the original default settings?

    Thank you for posting questions to Microsoft Q&A forum.

    1. PERFINCTHRESHOLD is a hidden setting, so I am not sure its default value. It maybe different depending on the power plans.
    2. You can resore the default settings by below methods:
      Settings > Power & sleep > Additional power settings > choose your power pan and click "Change plan settings" > Restore default settings for this plan
      195935-image.png Run "control.exe powercfg.cpl,,3" > Restore plan defaults

    Please akso check the link of Known Windows Power Subsystem GUIDs for your reference.
