Available in Standard and Datacenter editions — ideal for modern workloads that demand performance and built-in resilience. Setting one up? Our step-by-step guides cover Server 2025 Standard installation and activation and Server 2025 Datacenter installation and activation, plus migrating a domain controller to Server 2025.
Windows Server 2022
A proven enterprise-grade platform with advanced multi-layer security, hybrid cloud integration, and flexible application deployment. Windows Server 2022 Standard suits single-server environments, while the Datacenter edition is built for unlimited virtualisation and hyper-converged infrastructure (HCI) deployments.
Windows Server 2019
One of the most widely deployed server operating systems in the world. Windows Server 2019 brings Windows Defender Advanced Threat Protection (ATP), Shielded Virtual Machines, and deep Azure hybrid connectivity. Available in Standard, Datacenter, and Essentials editions to match any business size.
Windows Server 2016
Designed for the cloud era, Windows Server 2016 introduced Nano Server, containers, and Docker support to the Microsoft ecosystem. A rock-solid option for businesses running legacy applications alongside modern containerised workloads. Available in Standard, Datacenter, and Essentials.
Windows Server 2012 R2
Still found in many existing environments, Windows Server 2012 R2 suits maintaining legacy systems, test labs and isolated networks. Microsoft ended support on 10 October 2023 and its paid Extended Security Updates finished on 13 October 2026, so it no longer receives security updates. Standard, Datacenter, and Essentials licenses are all available.
Microsoft Exchange Server 2019
Run your own on-premises email, calendaring, and collaboration platform with Microsoft Exchange Server 2019. Available in Standard and Enterprise editions — giving you full control over your organisation's messaging infrastructure without recurring subscription fees.

Frequently Asked Questions
Are these Windows Server keys genuine?
Yes. All license keys sold by LicenceHouse are 100% genuine Microsoft licenses that activate via Microsoft's official servers. We do not sell cracked, pirated, or grey-market software.
What's the difference between OEM and Retail licenses?
OEM licenses are tied to the hardware they are first activated on and cannot be transferred to a new machine. Retail licenses can be transferred if you decommission the original server. Check each product listing for the specific license type.
Do I need a CAL (Client Access License) as well?
Yes — if users or devices will connect to your Windows Server, you will also need Client Access Licenses (CALs). Browse our Access Licences / CALs collection for RDS CALs and more.
Is there a trial before I buy?
Microsoft offers free 180-day evaluation ISOs for most server editions via the Microsoft Evaluation Center. Once you are ready to activate permanently, simply purchase your key from LicenceHouse and enter it into the running system — no reinstallation required.
What payment methods do you accept?
We accept all major credit and debit cards, PayPal, and other secure payment options at checkout.
