对 Win32_PowerPlan 的 Powershell 调用显示无效 class 错误

Powershell call to Win32_PowerPlan showing invalid class error

如何让这个 Powershell 命令起作用?这是否意味着我的非工作机器上的某些东西已损坏?要解决哪些步骤?

non-working/broken 机器上的命令:

PS> Get-CimInstance -Class "Win32_PowerPlan" -Namespace "root\cimv2\power"

Get-CimInstance : invalid class
At line:1 char:1
+ Get-CimInstance -Class "Win32_PowerPlan" -Namespace "root\cimv2\power ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo            : MetadataError: (root\cimv2\power:win32_PowerPlan:String) [Get-CimInstance, CimException
    + FullyQualifiedErrorId   : HRESULT 0x80041010,Microsoft.Management.Infrastructure.CimCmdlets.GetCimInstanceCommand

工作机器上的命令:

PS> Get-CimInstance -Class "Win32_PowerPlan" -Namespace "root\cimv2\power"

解决方案是重建 WMI 存储库。

起初我按照网上的说明从 MOF 文件重建,但这些都不起作用,所以我备份了存储库,然后从另一台机器上复制了一个工作存储库。
