Windows Server 2016 Datacenter

Unlock Unlimited Virtualisation with Windows Server 2016 Datacenter

Windows Server 2016 Datacenter is the definitive operating system for highly virtualised private and hybrid cloud environments. This is a perpetual, one-time licence designed for organisations that need to run an unlimited number of Windows Server instances on a single licensed physical server. If your infrastructure strategy relies on dense virtualisation, software-defined networking, and advanced security features to protect your workloads, this edition eliminates the complexity of counting operating system environments (OSEs).

This licence is built for IT professionals, system administrators, and enterprise architects managing large-scale data centres. The primary advantage is the unlimited virtualisation rights: you can deploy as many Windows Server virtual machines as your hardware can handle without purchasing additional licences. This makes it the most cost-effective choice for heavily virtualised servers. Your purchase is a genuine, verified licence delivered digitally, providing immediate access to a secure, identity-driven server platform with features like Shielded Virtual Machines and Storage Spaces Direct.

Key features and benefits

• Unlimited Virtual Machine Rights: Run an unlimited number of Windows Server instances on the licensed hardware. This eliminates per-VM licensing costs, delivering maximum return on investment for high-density virtualisation hosts.
• Shielded Virtual Machines: Protect your virtual machines from compromised administrators in the hosting fabric by encrypting them with BitLocker and restricting access to approved hosts only. This strengthens your compliance posture in multi-tenant environments.
• Storage Spaces Direct: Build highly available, scalable software-defined storage using local drives. This reduces the cost and complexity of traditional SAN or NAS arrays while delivering enterprise-grade performance and resilience.
• Software-Defined Networking (SDN): Centrally configure, manage, and monitor both physical and virtual network devices. This provides automated, policy-driven network deployment, ideal for dynamic data centre operations.
• Active Directory Federation Services (AD FS): Enable secure identity federation with support for multi-factor authentication and conditional access policies, allowing seamless single sign-on to applications hosted on-premises and in the cloud.
• Nano Server Deployment: Utilise a headless, 64-bit installation option that requires fewer updates and restarts. This minimises the attack surface and resource footprint for cloud-native and microservice applications.
• Windows Server Containers and Hyper-V Containers: Deploy applications faster with container technology. Choose between process-isolated Windows Server Containers for density or Hyper-V Containers for enhanced kernel-level isolation on the same host.
• Host Guardian Service: Create a protected fabric by attesting that Hyper-V hosts are running trusted, healthy code before they can run Shielded VMs. This provides a strong foundation for guarded fabric deployments.
• Digital Delivery: Receive your licence key and download instructions instantly via email. No physical media, no shipping costs, and no waiting—deploy your server infrastructure today.

What's included with your purchase

When you purchase Windows Server 2016 Datacenter from Lizensa, you receive a complete, activation-ready package delivered digitally. The transaction is for a perpetual licence, meaning it is a permanent, one-time purchase with no expiry date.

Your purchase includes:

• A Genuine Licence Key: A verified activation key for Windows Server 2016 Datacenter, sourced from authorised European distribution channels.
• Official Download Link: A direct link to download the official Microsoft installation media, ensuring you get a clean, unmodified ISO file.
• A VAT Invoice: A full, compliant invoice suitable for business accounting and tax purposes. Reverse charge is available for valid B2B intra-community transactions.
• Clear Activation Guide: Step-by-step instructions to guide you through installation and online or telephone activation.

Activation is straightforward. You download the software from the official Microsoft link we provide, install it on your server hardware, and enter the licence key when prompted. The key will activate the Datacenter edition with all its features. As this is a perpetual licence, you can reinstall the software on the same hardware as needed, though the licence is typically bound to the first machine it activates.

Which Windows Server edition is right for you?

Choosing the correct Windows Server edition is critical for licensing compliance and budget optimisation. The Windows Server 2016 family is primarily divided into Standard and Datacenter editions, with Essentials serving a separate, smaller-business role.

• Windows Server 2016 Standard: Ideal for physical or lightly virtualised environments. The Standard edition licences a single physical server and grants rights to run two virtual instances (OSE/Hyper-V containers). For every additional pair of VMs you need, you must purchase additional Standard licences and stack them on the same hardware. This model is cost-effective for low-density virtualisation.
• Windows Server 2016 Datacenter: This is the edition you are viewing. It is designed for highly virtualised and software-defined data centre environments. Its defining feature is unlimited virtualisation rights. You licence the physical cores on your server once, and you can run an unlimited number of Windows Server virtual machines on that host. This is the clear choice for high-density private clouds and large-scale Hyper-V deployments.
• Windows Server 2016 Essentials: Designed for small businesses with up to 25 users and 50 devices. It offers a simplified interface and pre-configured connectivity to cloud services but lacks the full virtualisation rights and advanced software-defined features of the Standard and Datacenter editions.

For enterprise IT, hosting providers, and any organisation with a strategy built on extensive virtualisation, Windows Server 2016 Datacenter is the optimal choice. It removes the administrative burden of tracking VM counts and provides the most predictable licensing model for scaling your virtual infrastructure.

FAQ — frequently asked questions

Is this a subscription or a one-time purchase?

This is a perpetual licence, which is a one-time purchase. There are no monthly or annual fees, unlike a subscription model.

What is the difference between Windows Server Standard and Datacenter?

The key difference is virtualisation rights. Windows Server 2016 Standard allows you to run two virtual machines per licence. Datacenter allows you to run an unlimited number of virtual machines on the licensed server. Datacenter is the correct choice for highly virtualised environments.

How fast will I receive my licence key?

Your licence key is delivered digitally and is typically available in under 60 seconds after payment confirmation. You will receive an email with the key, download link, and invoice, and it will also be stored in your Lizensa account.

Absolutely. Every licence sold by Lizensa is sourced from authorised European distributors and is 100% genuine. It is legally valid for activation and use in all 27 EU member states. You will receive a full VAT invoice as proof of your legal acquisition.

What if I have trouble activating the product?

Activation issues are rare, but if one occurs, our free multilingual technical support team is ready to help. Our purchase guide also includes step-by-step instructions for both online and telephone activation methods.

Can I reinstall or transfer this licence to another server?

You can reinstall the software on the same licensed hardware as many times as needed. However, a perpetual licence is generally tied to the first device it is activated on. It can only be transferred to new hardware if it is a warranty replacement for the original server, in accordance with Microsoft's licensing terms.

Does this licence work in my country?

Yes, this licence is valid for activation and use across all 27 member states of the European Union. It is not region-locked within the EU.

What payment methods do you accept?

Our Stripe-secured checkout supports a wide range of payment methods popular in Europe, including major credit cards, SEPA bank transfers, iDEAL, BLIK, and Google Pay.

Do you provide a VAT invoice?

Yes, a full and compliant VAT invoice is provided with every purchase. For B2B customers with a valid intra-community VAT ID, the reverse charge mechanism can be applied.

Key doesn't activate? We fix it or refund you.

Does this licence include the Desktop Experience GUI?

Yes, during installation you can choose between the "Server with Desktop Experience" option, which provides the familiar Windows graphical user interface, or the "Server Core" option, which is a headless, command-line managed installation for a smaller footprint.

Is this licence suitable for a small business with one server?

While it will work technically, Windows Server 2016 Datacenter is optimised for high-density virtualisation. For a single physical server running only one or two virtual machines, Windows Server 2016 Standard is usually a more cost-effective licensing choice.
