| VM rights | Unlimited Windows Server VMs on that host |

This listing is a genuine Windows Server 2019 Datacenter product key: a perpetual license for the virtualization edition of Windows Server 2019. When all physical cores of a host are licensed for Datacenter, that host may run unlimited Windows Server virtual machines, and it gains the software-defined storage, networking and security features that Standard lacks. Payment is one-time; there is no subscription.
Most people who buy 2019 Datacenter today are not building something new. They are adding a node to a Hyper-V or Storage Spaces Direct cluster that already runs 2019, replacing a failed host, or licensing a workload whose vendor certifies only 2019. For those jobs, matching the existing version exactly is worth more than the newest features.
If none of these apply, a newer version will serve you longer; see Windows Server 2025 Datacenter.
| Feature | 2019 Standard | 2019 Datacenter |
|---|---|---|
| Windows Server VMs per licensed host | 2 | Unlimited |
| Storage Spaces Direct | — | ✔ |
| Software-Defined Networking (Network Controller, SLB, gateways) | — | ✔ |
| Shielded VMs and Host Guardian Service | — | ✔ (Linux shielded VMs new in 2019) |
| Storage Replica | One partnership, one volume up to 2 TB | Unlimited |
| AVMA host | — | ✔ |
| Core roles, Hyper-V, failover clustering | ✔ | ✔ |
Need only a couple of VMs? The Windows Server 2019 Standard key does the job for less.
Although it is no longer the newest release, 2019 brought several Datacenter-relevant improvements that many clusters still depend on:
Unlimited applies to Windows Server operating system environments on the one physical host whose cores are all licensed for Datacenter. You can run as many Windows Server 2019 guests as the hardware allows, and Linux guests need no Windows license at all. The right does not extend to a second host, and it does not cover client operating systems such as Windows 10 or 11 for VDI, which are licensed separately.
Failover clusters and Storage Spaces Direct pools are designed for nodes running the same Windows Server version, so a replacement or expansion node for a 2019 cluster should run 2019 Datacenter too. License the new node for all of its physical cores, install the same updates as the existing nodes, then run cluster validation before adding it. When you eventually move the cluster to a newer release, Cluster OS Rolling Upgrade lets you upgrade one node at a time, but each upgraded node needs a license for the new version.
A Windows Server 2019 Datacenter host running Hyper-V can activate Windows Server 2019, 2016 and 2012 R2 guests through AVMA. Each guest gets Microsoft’s public AVMA key for its edition and activates via the host, with no internet connection or individual key required. Newer guests such as Windows Server 2022 cannot be activated by a 2019 host.
Yes, until January 9, 2029. Mainstream support ended on January 9, 2024, so the platform now receives security updates but no new features. Plan the next refresh for an estate built on this license before that date; our guide to Windows Server 2019 end of life lists the options. Remember that a host and its guests age together: when 2019 support ends, both the Hyper-V host and any Windows Server 2019 VMs stop receiving patches, so the migration plan should cover the guests as well as the host.
| Version | Support ends | Choose it when |
|---|---|---|
| Windows Server 2019 Datacenter | January 9, 2029 | Extending a 2019 cluster or meeting a 2019 certification |
| Windows Server 2022 Datacenter | October 14, 2031 | Matching 2022 hosts; Secured-core server features |
| Windows Server 2025 Datacenter | November 15, 2034 | New hosts, GPU partitioning, hotpatching |
The Server 2019 vs 2022 vs 2025 article covers what changed between the three.
The Datacenter license is counted per physical core, exactly like Standard: at least 8 cores per processor, at least 16 per server, and every core in the host covered. A two-socket host with 10 cores per CPU therefore needs 20 core licenses. If your host has more than 16 cores, tell us your hardware before ordering and we will confirm what you need.
Datacenter licenses the host and its VMs, not the users. Each user or device that authenticates to Windows Server needs a Windows Server CAL of version 2019 or later, and Remote Desktop users also need RDS CALs. For 2019 session hosts our Windows Server 2022 RDS CAL 50 user pack qualifies, because RDS CALs may be newer than the server as long as the RD license server runs a matching or newer version. See our Windows Server CAL explainer for the counting rules.
| Component | Minimum | Typical virtualization host |
|---|---|---|
| CPU | 1.4 GHz 64-bit with NX/DEP, CMPXCHG16b, LAHF/SAHF, PrefetchW; SLAT for Hyper-V | Dual-socket server processors |
| RAM | 512 MB (Core) / 2 GB (Desktop Experience) | Total VM memory plus a host reserve |
| Storage | 32 GB | SSD or NVMe; S2D needs local drives in each node |
| Network | Gigabit Ethernet | 10 GbE or faster with RDMA for S2D |
| Security | UEFI with Secure Boot | TPM 2.0 for Host Guardian attestation |
You pay once and the host remains licensed for good; there is no renewal. The license covers Windows Server 2019 only, with security updates until January 2029, and does not include rights to newer versions. For estates that will be retired or upgraded within the next couple of years, that is often the most economical way to stay compliant. The price is shown at the top of this page.

Instant delivery — exactly what I needed. Product activated successfully. No errors, no drama. Asked a question via chat and got a response pretty fast. 10/10 would order again.
Had to wait a bit longer than I hoped for the email, but it arrived. Followed the instructions on the site and it activated without problems. Much cheaper than going through Microsoft, and it’s completely legit.
The download link and key showed up in my email really fast. All the features I needed are there and working fine. Recommended.
Had to wait a bit longer than I hoped for the email, but it arrived. The activation steps weren’t totally clear but I figured it out. The product does work though, so can’t complain too much.
Solid purchase overall. Good price for a genuine licence. Exactly what I was after. It’s been reliable since day one. Recommended.
