Retrieve state of Windows 10 Power mode slider

Question

Is there any API to retrieve a state of Windows 10 Power mode slider?

I was looking at Windows.System.Power namespace. But PowerManager class seem to provide on

Answer 1

Change the position of the slider, and the registry key:HKLM\SYSTEM\ControlSet001\Control\Power\User\PowerSchemes\ActiveOverlayAc/DcPowerScheme will also change. ActiveOverlayAcPowerScheme is for non-battery powered and ActiveOverlayDcPowerScheme is for battery powered. However, Starting with Windows release 1903 the slider is available for AC only devices as an OEM opt-in feature. The values of the key ActiveOverlayAcPowerScheme and the corresponding slider modes are as follows:

Better Battery {961CC777-2547-4F9D-8174-7D86181b8A7A}

Better Performance {381B4222-F694-41F0-9685-FF5BB260DF2E}

Best Performance {DED574B5-45A0-4F42-8737-46345C09C238}

the ActivePowerScheme will be overlaid with ActiveOverlayAcPowerScheme. you can retrieve the key value to get the slider mode.
