Genuine, legal and guaranteed

Genuine retail licence

Every key is a genuine Microsoft product key, recycled from businesses that have upgraded or closed down. Once activated you receive Microsoft updates and security patches for as long as Microsoft supports that version, exactly like a brand-new retail licence.

Legal to buy and own

Reselling genuine, pre-owned software licences is legal under the first-sale doctrine (17 U.S.C. § 109). You are buying a real, transferable licence, not a copy.

Activation guaranteed

Online and telephone activation are both supported. If a key ever fails to activate, including being reported as already used, we replace it free of charge and stay with you until your product is fully activated. In the rare event we cannot get you activated, we will put it right.

About Windows Server 2025 - Datacenter 16 Core

Windows Server 2025 Datacenter is the newest Datacenter release, aimed at Hyper-V hosts, failover clusters and hyper-converged storage. This 16-core license covers 16 physical cores. Every physical core in the host must be licensed, with a minimum of 8 per processor and 16 per server. A host with two 16-core processors needs 32 core licenses. Microsoft supports Windows Server 2025 with security updates until November 14, 2034.

With all cores licensed, Datacenter gives unlimited Windows Server virtual machines and Hyper-V containers on the host, so the limit becomes your hardware rather than your license. For a host running more than a few Windows Server VMs, this is normally more practical than stacking Standard licenses. Windows Server 2025 user or device CALs are still needed for everyone who accesses the servers and are sold separately.

Datacenter adds Storage Spaces Direct, shielded VMs through Host Guardian Hyper-V support and the Network Controller for software-defined networking. In 2025, GPU partitioning works on both editions, but using it with failover clustering for unplanned downtime requires Datacenter. The 2025 release also brings SMB over QUIC to all editions, Active Directory improvements and hotpatching as a paid Azure Arc service. Processors must support SSE4.2 and POPCNT.

Windows Server 2025 - Datacenter 16 Core FAQ

Not for a standalone server. Standard supports GPU partitioning and live migration between standalone hosts for planned maintenance. If you need GPU-enabled VMs in a failover cluster to cover unplanned downtime, Microsoft requires Windows Server 2025 Datacenter.
License every physical core, with a minimum of 8 per processor and 16 per server. A single 24-core processor needs 24 core licenses, and two 32-core processors need 64. Logical processors from hyper-threading are not counted.
Yes. A Hyper-V host activated with Windows Server 2025 Datacenter supports Automatic Virtual Machine Activation, so supported Windows Server guests activate against the host using Microsoft's published AVMA keys instead of individual product keys.
No. On your own hardware, hotpatching for Windows Server 2025 Datacenter needs the server to be connected to Azure Arc and a separate paid hotpatch subscription. Standard monthly updates through Windows Update are available without it.
No. Core licenses cover the server only. Each user or device that accesses it needs a Windows Server 2025 CAL, and Remote Desktop users also need RDS CALs from /rds-cal/rds-cal-2025.
