GPO Library

This library is the result of several years of managing corporate infrastructure as well as my personal infrastructure under Active Directory—and, above all, a chronic aversion to doing the same thing twice. Every GPO documented here has been tested, refined, and deployed in production.

What You’ll Find Here

Each article follows the same structure:

• Why this GPO exists (the specific problem it solves)
• How it works (the underlying mechanisms, because knowing what you’re doing is still better)
• Step-by-step configuration (screenshots included, values verified)
• Verification (how to ensure it’s actually applied)

A note on the Central Store

Before diving into GPOs, here’s an important piece of information that affects everything: if you see the message “definitions retrieved from the local computer” in GPMC, then the Central Store is not configured. This means that the ADMX templates are loaded from the machine editing the GPO—and that the result may vary depending on the workstation used.

Best practice is to copy the entire C:\Windows\PolicyDefinitions\ directory from your server to:

\\domain\SYSVOL\domain\Policies\PolicyDefinitions\

robocopy C:\Windows\PolicyDefinitions C:\Windows\SYSVOL\sysvol\domain\Policies\PolicyDefinitions /E

Third-party ADMX files (OneDrive, Chrome, Brave, Firefox, etc.) are then added to this same folder. We’ll cover this in the relevant articles.
