Group Policy Objects (GPOs) are the core tools that administrators use to manage configurations and policies for users and computers in Active Directory Domain Services (AD DS). To create a GPO, you use the Group Policy Management Console (GPMC), which provides a single place to manage all your GPOs. When creating a GPO, you first define a clear goal for the policy, then link the GPO to the correct organizational units (OUs), and finally configure the specific settings, such as software installation rules or security policies.
GPOs rely on inheritance and enforcement to control how policies flow through the domain. Inheritance means that child OUs automatically receive policies from their parent OUs, which simplifies management. Enforcement overrides this normal flow by ensuring that a specific GPO's settings apply even if another policy conflicts with it. You can also block inheritance on a child OU to stop it from receiving parent policies, and the order of precedence determines which GPO wins when multiple policies apply to the same target.
To target only specific users or computers, you apply security filters or Windows Management Instrumentation (WMI) filters. Security filters limit a GPO's application to members of particular security groups, so only those users or computers get the policy. WMI filters use custom queries to check conditions, such as the operating system version or hardware specifications, and the GPO applies only when the query returns true.
In hybrid environments where on-premises AD DS extends into Azure, you must ensure policies remain consistent across both locations. Microsoft Entra Cloud Sync helps synchronize user and group memberships between on-premises and cloud domains, which allows for seamless policy management. This synchronization ensures that security baselines and configuration rules are upheld in both environments, helping maintain compliance with regulatory standards.

Inheritance causes child organizational units (OUs) to automatically receive policies from their parent OUs, whereas enforcement overrides this standard behavior to ensure a specific GPO's settings apply even if another policy conflicts. In addition, administrators can block inheritance on a child OU to stop parent policies from being received, while the order of precedence determines which GPO wins when multiple policies target the same object.
Security filters restrict GPO application to users or computers that belong to specific security groups, whereas WMI filters evaluate target systems using custom queries based on conditions like operating system versions or hardware specifications. A GPO linked to a WMI filter will apply only when its custom query evaluates to true.
Microsoft Entra Cloud Sync synchronizes user and group memberships between on-premises AD DS and cloud domains to facilitate seamless policy management. This synchronization ensures that configuration rules and security baselines are maintained consistently across both environments to help meet regulatory compliance standards.
