Microsoft P71-09445 Windows Server 2022 Datacenter 4 Core License

The Microsoft P71-09445 Windows Server 2022 Datacenter 4-Core Additional License allows organizations to expand their server licensing to match actual hardware configurations. Windows Server 2022 Datacenter requires every physical core in a server to be licensed, with a minimum of 16 cores per server. This 4-core pack lets you add licensing capacity in precise increments — essential for modern servers that commonly ship with 24, 32, or more cores across one or two processors. As a Datacenter edition license, it includes unlimited Windows Server virtual machine rights on the licensed physical host, making it the right choice for heavily virtualized environments running Hyper-V or other supported hypervisors.

It is important to understand that this is an additional license, not a standalone product. It does not include installation media, a product key, or Client Access Licenses (CALs), all of which must be obtained separately. This license is intended for organizations that already have a Windows Server 2022 Datacenter base license in place and need to cover additional cores on existing or new hardware. Windows Server 2022 Datacenter brings advanced security capabilities including Secured-core server, hardware-based isolation with virtualization-based security, and encrypted network connections by default — features that are available once the underlying cores are properly licensed with packs like this one.
