Windows Server 2016 License Keys

Should you still buy Windows Server 2016?

Windows Server 2016 reaches the end of extended support on 12 January 2027. After that date Microsoft stops releasing security updates for it. A 2016 licence is still useful when you:

• need to license or rebuild a server inside an existing 2016 environment,
• run a legacy application that is certified only for 2016,
• are bridging a short period before a planned migration.

For anything that will run beyond early 2027, choose Windows Server 2022 (updates until October 2031) or Windows Server 2025 (updates until November 2034).

Windows Server 2016 Standard vs Datacenter

Windows Server 2016 Standard covers two virtual machines per fully licensed server. Windows Server 2016 Datacenter allows unlimited virtual machines and adds Storage Spaces Direct and software-defined networking. Full details are in our Windows Server licence guide.

How Windows Server 2016 is licensed

Windows Server 2016 was the first version licensed per physical core instead of per processor. Every core must be licensed, with a minimum of 8 cores per processor and 16 per server. Users or devices connecting to the server need Windows Server CALs, and remote desktop users need RDS CALs as well. See Server CALs and RDS licences, or contact us to check what your server needs.

How delivery and activation work

• Your key is emailed immediately after payment, with installation instructions.
