The per-core packaged Datacenter 2025 — a 16-core base license with unlimited Windows Server virtual machines on the licensed host.

Activates on Microsoft’s servers
Buy a genuine Windows Server 2025 Datacenter 16 core product key and license a virtualization host the way large datacenters do: all cores licensed at Microsoft’s 16-core minimum, unlimited Windows Server guests on top. From the third VM onward this is the cheaper, cleaner alternative to stacking Standard licenses — and on the 2025 platform it comes with the longest support runway ever offered on a Datacenter edition.
Light virtualization (1–2 VMs)? Standard 2025 16 Core costs less. Same OS in the base listing: Server 2025 Datacenter. Previous generation: Server 2022 Datacenter 16 Core. Session hosts need RDS CALs for their users.
| Your host | Covered by this license? |
|---|---|
| 1 CPU, up to 16 cores | Yes — fully covered, unlimited VMs |
| 2 CPUs, 8 cores each | Yes — fully covered, unlimited VMs |
| 2 CPUs, 12 cores each (24 total) | Add 8 more core licenses — contact us for sizing |
| Larger hosts | All physical cores must be licensed — we’ll quote it |

|---|---|
| Unlimited virtualization | No per-VM licensing on the licensed host — ever |
| Storage Spaces Direct | Hyper-converged storage across nodes, NVMe-optimized in 2025 |
| Software-Defined Networking | Virtual networks, gateways, datacenter firewall |
| Shielded VMs | BitLocker-encrypted guests protected even from host admins |

Windows Server 2025 is serviced with mainstream support until October 9, 2029 and extended security updates until October 10, 2034. The license is perpetual — the longest-lived Datacenter platform you can buy today.
