Powershell Get-WmiObject generic-failure

问题描述

我正在为 wmi 查询（在管理员 Powershell 中运行）而苦苦挣扎，该查询因一般故障而失败...

Get-WmiObject -Class win32_pnpdevice

结果：

Get-WmiObject : Generic failure At line:1 char:14
+ Get-WmiObject <<<<  -Class win32_pnpdevice
    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject],ManagementException
    + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

这发生在 Windows 10 IoT、Windows 10 1809 Enterprise 和 Windows Embedded S7 上。对于 Windows Server 2016，查询工作正常...

我已经尝试用

修复 wmi

net stop winmgmt
winmgmt /salvagerepository %windir%\System32\wbem
winmgmt /resetrepository %windir%\System32\wbem
net start winmgmt

并且还重命名了 C:\Windows\System32\wbem 中的存储库文件夹并重建存储库。但查询仍然无效。

通过python调用查询会带来更多的错误代码：

>>> import wmi
>>> w = wmi.WMI()
>>> pnp = w.Win32_PnPDevice()
Traceback (most recent call last):

    result = self._oleobj_.Next(1)
pywintypes.com_error: (-2147217407,'OLE error 0x80041001',None,None)

有什么想法吗？
