Windows Server 2019 License Keys

Buy a genuine Windows Server 2019 licence key in Standard or Datacenter edition, plus Windows Server 2019 RDS CALs for remote desktop access. Keys are emailed instantly after payment, and Windows Server 2019 receives Microsoft security updates until 9 January 2029.

Why buy a Windows Server 2019 licence today?

Windows Server 2019 is still one of the most widely deployed server versions, and many line-of-business applications, accounting packages and ERP systems are certified for it. Buying a 2019 licence makes sense when you need to:

• match an existing Windows Server 2019 environment or domain,
• run software whose vendor supports 2019 but not yet 2022 or 2025,
• keep a lower cost per server for a project that will be retired before 2029.

For a brand-new deployment with no compatibility constraints, a newer version gets security updates for longer. Compare them below.

Windows Server 2019 vs 2022 vs 2025

Microsoft's mainstream support for Windows Server 2019 has ended, which means no new features, but security updates continue until January 2029.

Windows Server 2019 Standard or Datacenter?

Both editions are the same operating system. Windows Server 2019 Standard covers two virtual machines per fully licensed server, which suits physical servers and light virtualisation. Windows Server 2019 Datacenter allows unlimited virtual machines and adds Storage Spaces Direct, software-defined networking and shielded VM support. See the full Standard vs Datacenter comparison.

Cores, CALs and RDS CALs for Windows Server 2019

Windows Server 2019 is licensed per physical core. Microsoft requires every core to be licensed, with a minimum of 8 cores per processor and 16 per server. Each user or device that connects also needs a Windows Server CAL.

If users connect through Remote Desktop Services, every user or device additionally needs an RDS CAL. Our Windows Server 2019 RDS 50 Device CAL pack covers 50 devices; it does not include the server licence itself. Browse all Server CALs and RDS licences, or contact us with your core count and number of users and we will tell you exactly what to buy.

• Your Windows Server 2019 licence key is emailed immediately after payment, with download and installation instructions.

Windows Server 2019 FAQ

Is Windows Server 2019 still supported?

Yes. Mainstream support has ended, but Microsoft provides security updates for Windows Server 2019 until 9 January 2029.

Should I buy Windows Server 2019 or 2022?

Choose 2019 if your software or existing environment requires it. Otherwise Windows Server 2022 or 2025 gives you several more years of security updates.

Do I need CALs for Windows Server 2019?

Yes, in most cases. Each user or device accessing the server needs a Windows Server CAL, and remote desktop users also need RDS CALs. Public web workloads are an exception.

Which CALs work with Windows Server 2019?

Use CALs matching the version of the server people connect to. If you run a mix of server versions, tell us your setup and we will match the right CALs.
