Join nowWindows Server 2019 Datacenter is a perpetual, core-based server licence designed for organisations that run highly virtualised environments, software-defined data centres, and private-cloud infrastructure. This SKU covers 16 physical cores — the minimum licensing requirement per server — and grants unlimited Windows Server virtual machine rights on the licensed hardware. For IT managers, procurement leads, system integrators, and MSPs who need predictable licensing costs, clear audit trails, and a platform that matches existing 2019-generation application certifications, this is the edition that removes the VM-counting exercise from daily operations.
The immediate benefit is operational simplicity: licence the physical cores once, and you can run as many Windows Server VMs as the host hardware can support, without tracking per-VM entitlements. The licence is perpetual, meaning it does not expire, and it is supplied as a genuine digital licence with activation guidance, VAT invoice, and full EU consumer and business warranty protection. It is not a subscription, not a Client Access Licence (CAL), and not tied to a specific hardware profile beyond the core count — but CALs for users or devices accessing server services are still required unless a specific licensing exception applies.
When you complete your order, you receive a genuine Microsoft Windows Server 2019 Datacenter licence key delivered digitally to your email — typically in under 60 seconds. The licence is perpetual: you pay once, and the right to run the software on the licensed hardware does not expire. This is not a subscription, not a Software Assurance entitlement, and not an OEM key tied to a specific machine at first activation.
The activation method is determined by the fulfilment channel and will be clearly stated in your delivery email. Depending on your organisation's infrastructure, you may receive a Multiple Activation Key (MAK), Key Management Service (KMS) instructions, or a single-activation key. If your deployment requires a specific activation model — for example, air-gapped networks, large-scale KMS, or Active Directory-Based Activation — contact our support team before purchase so we can confirm compatibility.
Your purchase includes:
Please note: this SKU does not include Client Access Licences (CALs), Remote Desktop Services (RDS) CALs, or External Connector licences. Users or devices that access Windows Server services — file shares, print services, Active Directory, DHCP, DNS — require CALs unless a per-core or external-facing licensing exception applies. Keep your invoice, order confirmation, server hardware inventory, core count, and CAL records together as your compliance documentation.
Choosing between Windows Server editions is a licensing decision first and a feature decision second. The Datacenter edition is designed for organisations that need unlimited virtualisation rights on a single physical host. If you run more than a handful of Windows Server VMs on one machine, Datacenter is almost always the more cost-effective and administratively simpler choice compared to Windows Server Standard, which requires you to count and licence each VM individually beyond the two included OSEs (Operating System Environments).
Windows Server 2019 Datacenter is the right choice when:
Windows Server 2019 Standard is more appropriate when:
Windows Server 2019 Essentials (available through different channels) is suited for very small businesses with up to 25 users and 50 devices, and does not require CALs — but it lacks the virtualisation rights, storage features, and scalability of Datacenter.
If you are migrating from an older version such as Windows Server 2016 or 2012 R2, Datacenter 2019 preserves the same unlimited virtualisation model while adding the hybrid, security, and management improvements of the 2019 release. Downgrade rights are available if your application certification still requires an earlier version; contact our team to confirm eligibility based on your licensing agreement.
Before purchasing, verify that your server hardware meets or exceeds these requirements. The 16-core licence covers the minimum physical core count; if your server has more than 16 physical cores, you must purchase additional core packs to remain compliant.
| Component | Requirement | | --- | --- | | Operating system | Windows Server 2019 (this licence covers a fresh installation or an in-place upgrade from a supported version) | | Processor | 1.4 GHz 64-bit processor minimum; all physical cores in the server must be licensed — minimum 16 cores per server | | Memory | 512 MB minimum for Server Core; 2 GB or more recommended for Server with Desktop Experience; allocate additional RAM for virtualisation hosts, SQL workloads, and RDS roles | | Storage | 32 GB minimum for the operating system; additional space required for roles, updates, logs, page file, and workload data | | Display | Super VGA (1024 × 768) or higher resolution for graphical administration; Server Core can be managed remotely without a local display | | Network | Gigabit Ethernet adapter required; internet connectivity needed for licence activation, Windows Update, and hybrid Azure features | | Firmware | UEFI 2.3.1 or later with Secure Boot capability recommended for shielded VM and Host Guardian Service scenarios |
Language support: The server interface, administrative tools, and documentation are available in 24 languages: English, German, French, Spanish, Portuguese, Japanese, Polish, Dutch, Italian, Czech, Swedish, Danish, Finnish, Norwegian Bokmål, Greek, Hungarian, Romanian, Slovak, Slovenian, Croatian, Bulgarian, Estonian, Lithuanian, and Latvian. The licence key itself is language-agnostic; you can install any supported language version.
Compatibility notes: Windows Server 2019 is compatible with most server hardware certified for Windows Server 2016, but you should verify driver availability — particularly for storage controllers, network adapters, and out-of-band management — with your hardware manufacturer. Application certification should be checked against the specific workload: domain controllers, SQL Server, Exchange, SAP, and industrial control software each have their own support matrices. If your environment requires LTSC (Long-Term Servicing Channel) behaviour, Windows Server 2019 follows the LTSC release model with 10 years of support (mainstream support until January 2024, extended support until January 2029).
After purchase, your licence key and download instructions are delivered by email — typically within 60 seconds of payment confirmation. The email contains a link to the official Microsoft software download portal or ISO media, your unique product key or activation instructions, and a PDF activation guide.
Basic activation steps:
Reinstallation policy: A perpetual Windows Server licence can be reinstalled on the same licensed hardware as many times as needed — for example, after a hardware failure, storage replacement, or operating system corruption. The licence is tied to the physical server, not to a single installation instance. If you decommission the licensed server and replace it with new hardware, the licence does not automatically transfer; contact our support team to discuss your scenario.
If activation fails: Activation errors typically stem from edition mismatch (e.g., attempting to activate Standard with a Datacenter key), internet connectivity issues, or core-count compliance gaps. Our multilingual support team can help diagnose and resolve activation problems — contact us with your order number and the exact error message or screenshot.
When you buy a Windows Server 2019 Datacenter licence from Lizensa, you are not just purchasing a product key. You are buying a compliance asset that comes with the documentation, support, and consumer protections required by European law — and that matters the moment your procurement team, auditor, or IT manager asks for proof of licensing.
Every licence we sell is sourced through authorised European distribution channels and verified before delivery. Your order is processed through a Stripe-secured checkout that supports SEPA bank transfers, iDEAL, BLIK, Google Pay, and major credit and debit cards. The transaction is encrypted, and your payment data is never stored on our servers.
After payment, your licence key arrives by email in under a minute on average. The email includes a downloadable VAT invoice that meets EU invoicing requirements — B2B customers can request reverse-charge treatment where applicable. Because we are based in the European Union, your purchase is covered by the EU 14-day right of withdrawal for consumers, and by the full European warranty framework. If you encounter a licensing issue, our free multilingual support team — fluent in English, German, Dutch, French, and Polish — is available to help you activate, reinstall, or understand your licence terms.
Your licence is valid for activation across all 27 EU member states, plus the broader European Economic Area. There are no regional blocks, no geo-restrictions, and no subscription traps. What you buy today is what you own — a perpetual, genuine Windows Server 2019 Datacenter licence with unlimited virtualisation rights on the licensed hardware.
This is a one-time, perpetual licence purchase. You pay once, and the right to run Windows Server 2019 Datacenter on the licensed hardware does not expire. It is not a monthly or annual subscription, not an Azure consumption charge, and not a Software Assurance plan. Mainstream and extended support lifecycles from Microsoft apply, but the licence itself is permanent.
The critical difference is virtualisation rights. Datacenter allows unlimited Windows Server virtual machines on the licensed physical host. Standard includes rights for two Operating System Environments (VMs or containers) per licence; beyond two, you must purchase additional Standard licences for the same hardware. Datacenter also includes exclusive features like Storage Spaces Direct, Software Defined Networking, and Shielded VMs.
Our digital delivery system sends your licence key and download instructions by email in under 60 seconds on average after payment confirmation. In rare cases of manual fraud review, delivery may take up to 15 minutes during business hours. If you have not received your email within 30 minutes, check your spam folder and then contact our support team.
Yes. Every licence we sell is sourced from authorised European distributors and is genuine, legally valid, and fully compliant with Microsoft's licensing terms. You receive a VAT invoice that serves as proof of purchase for audit and accounting purposes. We do not sell OEM keys as retail, MSDN keys, or grey-market imports.
Contact our multilingual support team with your order number and the exact error message or code you are seeing. Common issues — edition mismatch, internet connectivity, core-count gaps — can usually be resolved quickly. If the key is genuinely faulty, we will replace it under our warranty.
You can reinstall the licence on the same physical server as many times as needed — for example, after a storage failure or OS corruption. Transferring the licence to entirely new hardware is generally not permitted under the perpetual licence terms unless the original server is permanently decommissioned and the licence was acquired as a full retail or volume licence. Contact our support team with your specific scenario before assuming transferability.
Yes. The licence is valid for activation and use in all 27 European Union member states, as well as Iceland, Norway, Liechtenstein, and Switzerland. There are no geographic activation blocks within the EEA. The server interface supports 24 languages, so you can install and administer the system in your local language.
We accept SEPA bank transfers, iDEAL (Netherlands), BLIK (Poland), Google Pay, Visa, Mastercard, and American Express. All payments are processed through Stripe's PCI-DSS Level 1 compliant platform. Your card details are never stored on our servers.
Yes. A full VAT invoice is included with every purchase and delivered alongside your licence key. The invoice shows our EU VAT number, your billing details, the product description, and the transaction amount. B2B customers in the EU can request reverse-charge VAT treatment where applicable under the EU VAT Directive.
Under EU consumer law, you have a 14-day right of withdrawal for digital goods purchased online. If you have not activated or downloaded the licence, we will issue a full refund. Once a licence key has been viewed or activated, refund eligibility is assessed case by case. Faulty or non-activating keys are replaced or refunded under our warranty.
Yes, in most scenarios. The Windows Server licence covers the server software itself, but users or devices that access server services — such as file shares, print services, Active Directory, DHCP, or DNS — require a Windows Server CAL unless a specific exception applies (for example, anonymous web access or certain external user scenarios). CALs are sold separately and are not included in this SKU.
Microsoft requires that all physical cores in a server be licensed, with a minimum of 16 cores per server. This SKU covers exactly 16 cores. If your server has more than 16 physical cores — for example, a dual-processor system with 10 cores per CPU (20 cores total) — you must purchase additional 2-core or 16-core packs to cover the remaining cores. Our support team can help you calculate the correct core count for your hardware.
