Is there a 2025 domain functional level? As of now, Microsoft has not released a 2025 domain functional level. The latest available domain functional level is Windows Server 2022. Understanding domain functional levels is crucial for IT professionals managing Active Directory environments, as these levels determine the available features and capabilities.
What Are Domain Functional Levels?
Domain functional levels are configurations in Active Directory that enable specific features. These levels are set within a Windows Server domain and dictate the features that can be used. Higher functional levels support more advanced features, but they also require all domain controllers to run a compatible version of Windows Server.
Key Features of Domain Functional Levels
