Windows Server License
A Windows Server licence is bought per server, and for most editions it is licensed by physical core rather than per machine. That one detail is where most orders go wrong, so it is worth two minutes before you buy: count the physical cores in the server, then pick the licence that covers them.
If you are not sure, send us the server model and we will confirm the right licence and core count before you pay. Every key below is genuine, arrives by email within minutes, and comes with installation support included.

Windows Server — frequently asked questions
How is Windows Server licensed?
By physical core for Standard and Datacenter, with a minimum of 16 cores per server and 8 per processor. Essentials is licensed per server for small deployments. Send us your server specification and we will confirm what you need.
Do I also need CALs?
Yes, in most deployments. The server licence covers the operating system; Client Access Licences cover the users or devices that connect to it. Remote Desktop sessions need separate RDS CALs on top.
What is the difference between Standard and Datacenter?
Both have the same features. The difference is virtualisation rights: Standard allows two virtual machines per licence, Datacenter allows unlimited. If you virtualise heavily, Datacenter works out cheaper.
Can you help me size this?
Yes. Tell us the server model, core count, how many users or devices connect, and whether you run virtual machines. We will tell you exactly what to buy before you spend anything.
How quickly will I get my product key?

Are these genuine Microsoft licences?
Yes. Every key is a genuine Microsoft licence and comes with full activation support. Vaneyo is an authorized reseller and holds a Microsoft partnership certificate.
Is it a one-time payment?
