Buy Microsoft Windows Server 2025 Datacenter with core-based licensing for highly virtualized server environments. Designed for businesses and enterprise infrastructure, Datacenter edition provides unlimited Windows Server virtualization rights on fully licensed physical servers, alongside advanced security, storage and hybrid management capabilities.
Core licenses cover processor cores, not individual users or devices. Each physical server requires sufficient core licensing to meet Microsoft’s licensing rules.
Windows Server 2025 Datacenter is Microsoft’s server operating system for organizations running highly virtualized workloads and software-defined infrastructure.
Unlike Standard edition, Datacenter provides unlimited virtualization rights once every physical processor core on the server is correctly licensed. It also includes advanced infrastructure features for centralized storage, virtual machine protection and scalable server management.
Run an unlimited number of Windows Server virtual machines on a fully licensed physical host, subject to hardware capacity and Microsoft’s licensing terms.
Datacenter also supports unlimited Windows Server containers, including containers with Hyper-V isolation. This makes it particularly suitable for virtualization-intensive infrastructure without repeatedly licensing the same physical server for additional Windows Server virtual machines.
Storage Spaces Direct combines storage from compatible servers into a software-defined storage system, reducing dependence on dedicated storage arrays.
Together with Windows Server Failover Clustering, it supports resilient infrastructure and helps maintain availability during supported hardware failures and maintenance operations.
Shielded VMs help protect sensitive virtual machines from unauthorized access and manipulation. Windows Server 2025 Datacenter also supports security capabilities such as Credential Guard, BitLocker encryption and enhanced Active Directory services.
These features provide additional protection for virtualized workloads and enterprise server environments when correctly configured.
Windows Server 2025 supports Azure Arc integration, allowing organizations to connect compatible on-premises servers to Azure management services.
The platform also supports SMB over QUIC for encrypted remote file access and improved Active Directory scalability, helping businesses manage hybrid environments securely. Optional Azure services may involve separate charges.
Windows Server 2025 Datacenter uses Microsoft’s Per Core/CAL licensing model.
For licensing based on physical processor cores, the requirements are:
Choose the 16, 32, 64 or 96-core licensing option that meets your physical server’s requirements.
Unlimited virtualization rights apply only after the entire physical server is correctly licensed. Each additional physical host requires its own appropriate licensing. A 16-core option does not provide full licensing for a server that requires more than 16 core licenses.
For users or devices accessing Windows Server, appropriate Windows Server CALs are generally required. Remote Desktop Services access may also require separate Windows Server RDS CALs.
Before installing Windows Server 2025 Datacenter, verify that your hardware meets the following minimum requirements.
Additional hardware, storage and networking requirements apply to advanced features such as Storage Spaces Direct and shielded VMs.
See the official Windows Server 2025 hardware requirements for compatibility details.
After completing your purchase, you receive a Windows Server 2025 Datacenter digital product key for your selected core licensing option.
To install and activate:
This product provides a digital license key. Physical server hardware, Windows Server CALs and licenses for additional physical hosts are not included.
Live-chat assistance is available through the store.
Datacenter edition is designed for organizations that need unlimited Windows Server virtualization rights and advanced software-defined infrastructure features such as Storage Spaces Direct and shielded VMs.
If your infrastructure requires only limited virtualization, Windows Server 2025 Standard Core-Based may be a more suitable option. Standard provides rights for up to two Windows Server operating system environments per fully licensed physical server, with additional licensing required for more.
