Using 'Get-GPInheritance' Command in Powershell 7

New Contributor

Using the 'Get-GPInheritance' command in Powershell 7 returns the GPOLink class rather than the GPO name for each GPO listed in the 'InheritedGpoLinks' property.

 

Get-GPInheritance -Target $ou | Select-ExpandProperty InheritedGpoLinks | FT

 

But the same command outputs the GPO names successfully in Windows PowerShell 5.1. 

How can I get this to work in Powershell 7?

mmm.

I am checking the issue and notice that there are a lot of different between running the command on Powershell 5.1 (Infrastructure version) vs Powershell 7

even the object type and the return is different, 

Powershell 5.1, Notice that the name is GPOLink, which seems to be an object holding the value 

 

PS C:\Users\Administrator> ((Get-GPInheritance -Target $ou ).InheritedGpoLinks)[0].gettype()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     False    GpoLink                                  System.Object

 

 Powershell 7.1, Notice that the Value type is String not GPOLink

 

PS C:\Program Files\PowerShell\7> ((Get-GPInheritance -Target $ou ).InheritedGpoLinks)[0].gettype()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     String                                   System.Object

 

 

Even when you run Get-GPInheritance -Target $ou 

Powershell 5.1: will return the GPNmae

Powershell 7.1: will return Microsoft.GroupPolicy.GpoLink

I will do more checks on this, this is maybe because the GroupPolicy module was written and tested in PS5.1 but not 7

Interesting. Thanks for looking into this.
