Windows注册表设置对应于Powercfg.exe /setAcvalueIndex

Question

在我的powershell脚本中，我使用

powercfg /setacvalueindex 381b4222-f694-41f0-9685-ff5bb260df2e 238c9fa8-0aad-41ed-83f4-97be242c8f20 29f6c1db-86da-48c5-9fdb-f2b67b1f44da 0

我想稍后验证上述值是否已设置。我该如何验证？

我找不到此set命令选项的任何获取版本，例如getAcvalueIndex？

或我们执行此操作时是否有设置的注册表设置，以便我可以在Windows注册表中验证它？

也许我们可以使用PowerReadACValue(https://learn.microsoft.com/en-us/windows/desktop/api/powersetting/nf-powersetting-power-powerreadacvalue(

例如(http://www.reza-aghaei.com/how-to-to-get-value of-Advanced-power-settings/(

[DllImport("powrprof.dll")]
static extern uint PowerGetActiveScheme(
    IntPtr UserRootPowerKey,
    ref IntPtr ActivePolicyGuid);
[DllImport("powrprof.dll")]
static extern uint PowerReadACValue(
    IntPtr RootPowerKey,
    ref Guid SchemeGuid,
    ref Guid SubGroupOfPowerSettingGuid,
    ref Guid PowerSettingGuid,
    ref int Type,
    ref int Buffer,
    ref uint BufferSize);
public static void Foo()
{
    var activePolicyGuidPTR = IntPtr.Zero;
    PowerGetActiveScheme(IntPtr.Zero, ref activePolicyGuidPTR);
    var activePolicyGuid = Marshal.PtrToStructure<Guid>(activePolicyGuidPTR);
    var type = 0;
    var value = 0;
    var valueSize = 4u;
    PowerReadACValue(IntPtr.Zero, ref activePolicyGuid,
        ref GUID_SLEEP_SUBGROUP, ref GUID_STANDBY_TIMEOUT,
        ref type, ref value, ref valueSize);
    var message = $"Sleep after {value} seconds.";
}
