Cleaning up unlinked Group Policy objects in Active Directory with Powershell

Just a quick script below to run through all unlinked GPO’s in a domain, back them up, export a report and then remove them.

Sweet and short but useful. (# Comment the remove line if you don’t want to remove any)

[cc lang=“Powershell”] Import-Module GroupPolicy
 $backupPath=”C:\Users\jeffrl-p\Desktop\Backup_GPO”


if (-Not(Test-Path -Path $backupPath)) {
 mkdir $backupPath
 }
 


Get-GPO -All

Sort-Object displayname

Where-Object { If ( $_

Get-GPOReport -ReportType XML

Select-String -NotMatch “” )

{ $backupReportPath = $backupPath + “\” + $_.DisplayName + “.html” Backup-GPO -Name $_.DisplayName -Path $backupPath Get-GPOReport -Name $_.DisplayName -ReportType Html -Path $backupReportPath $_.DisplayName

Out-File $backupPath + “UnLinked_GPO_List.txt” -Append $_.Displayname

remove-gpo -Confirm } } [/cc]
