Powershell – Retrieve the GPOs linked to AD OU 

# retrieve the GPOs linked to AD OU  

# initially we need to get the 2 modules AD and GPO 
Get-Module activedirectory.grouppolicy 

# Create a variable for the OU that we will be looking at  
$OU = "OU=ZhyHealth,DC=internal,DC=Zhyhealth,DC=org,DC=au" 

# change this OU based on the required lookup 

Get-ADOrganizationalUnit $OU 
# For this OU the property we will be looking at is the LinkedGroupPolicyObjects 

$LinkedGPOs = Get-ADOrganizationalUnit $OU | Select-Object -ExpandProperty LinkedGroupPolicyObjects 

$LinkedGPOs 

$linkedGPOGUIDs = $LinkedGPOs | ForEach-Object{$_.Substring(4,36)} 

$linkedGPOGUIDs 

# Now we have retrieved the GUIDs, we need to loop through these GUIDs and use the Get-GPO  

# to fetch the DisplayName of GPO 

$linkedGPOGUIDs | ForEach-Object {Get-GPO $_ Select-Object DisplayName }
