Group Policy Reference
A comprehensive Microsoft Windows Group Policy reference — searchable database of GPO settings with registry paths, supported OS versions, configuration steps, security implications, and real-world use cases. Built for sysadmins managing Active Directory, Intune, and standalone Windows.
What is a Group Policy?
A Group Policy Object (GPO) is a configuration setting in Windows that defines how computers and user accounts behave. Each policy maps to one or more registry values, applies to a specific scope (Computer or User), and is bundled in an ADMX (Administrative Template) file. This reference indexes Microsoft's ADMX catalog with detailed explanations, registry mappings, and operational guidance you won't find on the official Microsoft Learn pages.
