我是Windows电源管理新手，甚至是WMI新手，但始终欢迎有学习机会

使用PowerShell和WMI，我想将“高性能”电源计划的“盖关闭操作”、“电源按钮操作”和“睡眠按钮操作”设置为“不做任何事情”选项，最后将活动电源计划设置为“高性能”电源计划。我有一个有效的解决办法，但我怀疑这是否是一个适当的解决办法

我的问题的关键是，所有的计划、子组、操作、可用值等都是用guid标识的，我已经了解到这些guid可能会因系统而异（特别是通过组策略应用的情况下）。在我的解决方案中，我设法避免硬编码guid，但最终只会导致硬编码值，例如“电源和盖按钮”、“盖关闭操作”、“不做任何事情”等，在非英语版本的Windows中可能会有所不同，也可能不会有所不同。（顺便说一下，我使用的是Windows 8.1。）

我的问题 以编程方式发现每个计划、子组、操作、可用值等的GUID的正确方法是什么

function Set-PowerSettingDataIndexValue
{
    <#
    .Synopsis
        Sets the value associated with a specified power setting for both AC and DC power.
    .Description
        This function is somewhat similar to running the two commands
        'POWERCFG /SETACVALUEINDEX <SCHEME_GUID> <SUB_GUID> <SETTING_GUID> <SETTING_INDEX>'
        and
        'POWERCFG /SETDCVALUEINDEX <SCHEME_GUID> <SUB_GUID> <SETTING_GUID> <SETTING_INDEX>'
        except that the <SUB_GUID> is implied by the $PowerSettingDefinitionGuid
    .Example
        Set-PowerSettingDataIndexValue "{8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c}" "{7648efa3-dd9c-4e3e-b566-50f929386280}" 3

function Set-PowerButtonAndLidActions
{
    <#
    .Synopsis
        Sets the power button, sleep button and lid actions to do nothing effectively disabling these buttons.
    .Description
        This function modifies every existing power plan to effectively disable the power button, sleep button and
        lid action. Additonally this function will set the "high performance" power plan as the active power plan.

您可以使用
获取CIMInstance
列出几乎所有这些。电源计划都在
Win32\u电源计划
类中，因此：

Get-CimInstance -classname Win32_PowerPlan -Namespace "root\cimv2\power"
这将列出计算机上的所有计划。您可以在上找到所有这些信息。甚至还有PowerShell示例

从这里，您只需解析出所需的信息。
ElementName
属性显示了某人在进入控制面板中的电源设置GUI时会看到的内容。
InstanceID
是您可以找到GUID的地方，尽管您可能需要执行以下操作：

Get-CimInstance -Namespace "root\cimv2\power" -class Win32_PowerPlan|Select ElementName,@{l='GUID';e={$_.instanceid.substring(20)}}
其余部分应在
Win32\u PowerSetting
和
Win32\u PowerSettingSubgroup
中找到。您应该能够浏览该站点，找到其他相关类，以获取所需信息。

$powerplan=get-wmiobject -namespace "root\cimv2\power" -class Win32_powerplan | where {$_.IsActive}

$powerSettings = $powerplan.GetRelated("win32_powersettingdataindex") | foreach {
 $powersettingindex = $_;

 $powersettingindex.GetRelated("Win32_powersetting") | select @{Label="Power Setting";Expression={$_.instanceid}},
