Volume Licensing (MAK/KMS): Multiple Activation Keys (MAK) are used for a specific number of activations, while Key Management Service (KMS) uses a local host to activate clients within a network.
Automatic Virtual Machine Activation (AVMA): Specifically for virtual machines running on a Windows Server Datacenter host. 2. Standard Activation via the Settings App

Active Directory-Based Activation (ADBA): Ideal for domain-joined servers. It stores activation objects in AD, allowing servers to activate automatically upon joining the domain without needing individual keys.
Key Management Service (KMS): A centralized service for large environments. Clients activate against an internal KMS host every 180 days. Related search suggestions: functions
