Comparison
Windows Server Standard vs Datacenter
Server 2022 Standard vs Datacenter — pricing, virtualization rights, Storage Spaces Direct, Shielded VMs and the 12-VM break-even rule.

Standard and Datacenter editions of Windows Server include the same core OS — same kernel, same role binaries. The differences are virtualization rights, software-defined infrastructure features, and price.
The simple rule: under 12 VMs on the host → Standard. Over 12 VMs or any need for software-defined networking / Shielded VMs → Datacenter.

Which one should you buy?
Pick Standard for: file/print servers, domain controllers, single-app hosts, light Hyper-V (≤2 VMs per license, stack licenses for more).
Pick Datacenter for: hyper-converged infrastructure, dense Hyper-V hosts, hosting providers, anyone using SDN or Storage Spaces Direct.
Before choosing a licence
1. Check the exact edition, Windows or macOS compatibility and number of devices covered. A Windows-only key does not install Office for Mac.
2. Distinguish personal, commercial and server use. Virtual machines, shared devices and remote access can require additional licences.
3. Keep the invoice and licence terms. Check transfer rights and support dates: a perpetual licence does not mean perpetual security updates.
Successful activation alone does not prove permission for every use. The applicable Microsoft licence terms take precedence.

Can I stack Standard licenses for more VMs?
