Not sure which license you need?
Three questions that decide most orders.
Standard or Datacenter?
Standard covers 16 cores and two virtual machines. Datacenter removes the VM limit. The crossover depends on how many VMs you run.
Do you need CALs?
Every user or device connecting to a Windows Server needs a Client Access License, sold separately. Essentials is the exception.
Installing before you buy?
Microsoft's evaluation ISO runs for 180 days and converts to a full license with a product key. No reinstall needed.
How it works
From order to activated server, usually under ten minutes.
Choose your license
Every listing states the cores covered, the VM allowance, and whether CALs are included.

Why buy from Ms Server
Four things we can actually prove.
Genuine Microsoft licenses
Every key is sourced to be activated with Microsoft, not a workaround.
Invoiced by a registered company
Dataleb, registered in France, VAT number on every invoice.
Delivered in minutes, not days
Digital delivery by email. No shipping, no waiting, no physical media.
Support that knows licensing
Questions about cores, CALs or activation get answered by someone who understands the licensing model.
Buying Microsoft server licenses
Ms Server sells perpetual licenses for Microsoft server products: Windows Server from 2008 R2 through 2025, SQL Server, SharePoint Server, and the Client Access Licenses that go with them. Every license is a one-time purchase — no subscription, no renewal, no expiry.
Which Windows Server edition fits your setup
Windows Server is licensed per physical core, with a minimum of 8 cores per processor and 16 per server. Standard allows two virtual machines on a fully licensed host; Datacenter removes that limit and adds Storage Spaces Direct, Storage Replica and Shielded VMs. Essentials is a different model entirely — licensed per server, capped at 25 users and 50 devices, with access rights included instead of separate CALs.
Client Access Licenses, explained briefly
Outside Essentials, the server license covers the machine, not the people using it. Each user or device connecting to it needs a CAL. User CALs suit teams where people use several devices; Device CALs suit shared workstations used across shifts. Remote Desktop Services requires its own separate RDS CAL on top of the standard one.
Older versions still available
Windows Server 2012 R2 and 2008 R2 have reached end of extended support, but remain in service on isolated systems and legacy applications that can't migrate. Licenses are still available here for those cases. For anything new, 2022 or 2025 is the right starting point.
Delivery and activation
Licenses are delivered by email, usually within minutes of payment confirmation, along with an invoice and activation instructions. Activation is done through Microsoft, online or by phone. If a key fails to activate, contact us and we'll replace it.
