Error calling get-wmiobject for Win32_powerplan

Question

I'm trying to return the Win32_PowerPlan in PowerShell 7 on Windows 11 with the following code:

get-wmiobject -namespace "root\cimv2\power" -class Win32_powerplan

However, I get the output:

get-wmiobject : 
At line:1 char:1
+ get-wmiobject -namespace "root\cimv2\power" -class Win32_powerplan
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], COMException
    + FullyQualifiedErrorId : GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

Not sure what could be going on or how to get better error logs. The official docs use this exact code snippet, so not sure what it should change to if it's wrong.

Answer 1

It would appear that, to retrieve the information you are seeking, PowerShell needs to be run in "elevated" mode (ie, "Run as Administrator").

When doing so, I see the information as intended; however, when running 'normally' (even though I'm logged on with admin rights), I see the same error message that you have reported.
