A way to search a specific setting over all GPOs

Generate a GPO Report over your Domain

You can generate a GPO Report over your Domain either in a XML or HTML file and then search through that file.

To generate a XML use this command:

Get-GPOReport -All -Domain "domain.com" -Server "DC01" -ReportType XML -Path "C:\GPOReports\GPOReportsAll.xml"

To generate a HTML file you can use this command:

Get-GPOReport -All -Domain "domain.com" -Server "DC01" -ReportType HTML -Path "C:\GPOReports\GPOReportsAll.html"

All GPO settings will be included in this Report file. So you can search through that file and find your settings.
