*PowerShell export of Active Directory Group Policy Objects using native Get-GPO and Export-Csv commands to establish a baseline inventory before infrastructure changes.*

Maintaining visibility into Group Policy Objects (GPOs) is critical before domain consolidation, tenant migration, or infrastructure modernization.

Below are seven native PowerShell commands used to generate a full GPO inventory, validate configurations, and export audit-ready reports.

All commands use built-in GroupPolicy modules — no third-party tools required.

1. Export GPO Summary Inventory

Exports high-level metadata for all GPOs in the domain.

Get-GPO -All -Domain "yourdomain.local" |
Select-Object DisplayName, Id, GpoStatus, CreationTime, ModificationTime |
Export-Csv "C:\Temp\GPO_Summary.csv" -NoTypeInformation

This provides:
• GPO Name
• GUID
• Status (Enabled/Disabled)
• Creation Date
• Last Modified Date

2. Generate Full XML Reports for All GPOs

Creates detailed configuration exports for forensic or migration analysis.

New-Item -ItemType Directory -Path "C:\Temp\GPOReports" -Force

Get-GPO -All -Domain "yourdomain.local" |
ForEach-Object {
    Get-GPOReport -Guid $_.Id -ReportType XML -Path "C:\Temp\GPOReports\$($_.DisplayName).xml"
}

XML reports include:
• Security settings
• Registry policies
• Administrative templates
• Computer/User configuration details

3. Generate Executive-Readable HTML Report

Get-GPOReport -All -Domain "yourdomain.local" -ReportType HTML -Path "C:\Temp\All_GPOs_Report.html"

Useful for:
• Leadership review
• Change control documentation
• Audit preparation

4. Identify Fully Disabled GPOs

Get-GPO -All -Domain "yourdomain.local" |
Where-Object {$_.GpoStatus -eq "AllSettingsDisabled"} |
Select DisplayName, Id, GpoStatus |
Export-Csv "C:\Temp\Disabled_GPOs.csv" -NoTypeInformation

Helps identify cleanup opportunities before migration.

5. Validate a Specific GPO (Live Proof Command)

Get-GPO -Name "Default Domain Policy" -Domain "yourdomain.local"

Useful for:
• Live validation
• Troubleshooting
• Demonstrating configuration integrity

6. Export WMI Filters

Get-GPWmiFilter -Domain "yourdomain.local" |
Select Name, Description |
Export-Csv "C:\Temp\WMI_Filters.csv" -NoTypeInformation

Important when:
• GPOs are scoped using OS filters
• Planning domain consolidation

7. Create a Baseline Snapshot Before Major Change

Get-GPO -All -Domain "yourdomain.local" |
ForEach-Object {
    Get-GPOReport -Guid $_.Id -ReportType HTML -Path "C:\Temp\Baseline\$($_.DisplayName).html"
}

This creates a point-in-time snapshot for rollback or comparison.

Why This Matters

Before:

• Domain merge
• Tenant consolidation
• Intune migration
• Security hardening
• Infrastructure cleanup

You need visibility.

PowerShell provides:
• Repeatability
• Transparency
• Audit defensibility
• No dependency on external tooling
