Windows Server Licensing, Answered
Buying server infrastructure licenses is more nuanced than desktop software. Here are the questions our customers ask most before purchasing.
Windows Server Standard is licensed for up to 2 virtual machines (VMs) per licensed server, making it the right choice for most general-purpose workloads. Windows Server Datacenter provides unlimited VM rights on the licensed host, it's the cost-effective choice for highly virtualised environments running 4 or more VMs per physical server. Both editions are functionally identical at the OS level; the difference is purely in virtualisation rights.
All Windows Server licenses we sell are perpetual licenses, a one-time purchase that gives you the right to run that version of Windows Server indefinitely. There is no annual renewal fee, no expiry date, and no subscription to cancel. This is the traditional, owned licensing model, as opposed to Azure or Microsoft's cloud-hosted alternatives.
Since Windows Server 2016, Microsoft moved from socket-based to core-based licensing. Each physical server must be licensed for a minimum of 16 cores (sold in 2-core packs). All physical cores on the server must be licensed, you cannot cherry-pick. We calculate the exact number of core licenses required for your hardware and build a precise quote, so you never over- or under-buy.
Yes, in most deployments. Every user or device that accesses Windows Server services (file shares, RDS, print, etc.) requires a Windows Server CAL. You choose between User CALs (one per user, regardless of device count) or Device CALs (one per device, regardless of user count). Remote Desktop Services (RDS) requires additional RDS CALs on top. Our advisors run through your access patterns to recommend the most cost-effective CAL model.
For new deployments, we recommend Windows Server 2022, which is Microsoft's current release with the longest remaining support lifecycle (mainstream support through 2026, extended support through 2031). Windows Server 2019 remains a solid choice if you have existing infrastructure or software compatibility requirements. Windows Server 2016 is still available but approaching end of mainstream support, we typically recommend it only for specific compatibility scenarios.
Yes, this is one of the most valuable aspects of perpetual licensing. Through Microsoft's Azure Hybrid Benefit program, you can apply your on-premises Windows Server licenses to Azure VMs, significantly reducing hourly compute costs (up to 40% savings on Azure VMs). Our advisors calculate exactly how much you'd save before you purchase.
Electronic delivery is typically completed same business day. You'll receive your license key, product ID, and step-by-step activation instructions via email. For enterprise orders with Software Assurance or Volume Licensing requirements, timelines may vary slightly, we'll confirm at the time of quote.
Absolutely. All licenses are procured directly through Microsoft's Cloud Solution Provider (CSP) program. This means every key is registered against your organisation's Microsoft tenant, fully traceable, and compliant with Microsoft's Software Asset Management (SAM) requirements. You'll never face an audit finding for a license purchased through us.
