If your project calls for a specific edition (a cluster, a dense virtualization host), email our <a href=\"\/support\/\">support team<\/a> before ordering and we will tell you whether our license fits. You can also browse the <a href=\"\/product-category\/server\/\">Windows Server category<\/a>.<\/p>\n<h2>Core-based licensing: the counting rules to know<\/h2>\n<p>Since the 2016 version, Microsoft licenses the Standard and Datacenter editions per physical core rather than per processor. Three rules avoid the usual mistakes:<\/p>\n<ul>\n<li>every physical core in the server must be covered;<\/li>\n<li>a minimum of <strong>8 cores per processor<\/strong> and <strong>16 cores per server<\/strong> applies, even on a small 4-core tower;<\/li>\n<li>Microsoft sells core licenses in packs of 2 and 16 cores, combined up to the exact total.<\/li>\n<\/ul>\n<p>A concrete example: a dual-processor server with 12 cores each needs 24 core licenses. The Essentials edition escapes this calculation, since it is licensed per server, within a limit of one processor and 10 cores.<\/p>\n<p><strong>Good to know:<\/strong> before ordering, check the number of physical cores in your server with the PowerShell command <code>Get-CimInstance Win32_Processor<\/code>. If your hardware goes beyond a typical small-business server (several processors, a high core count), email our support team first so we can confirm the right purchase.<\/p>\n<h2>CALs: who needs them and which type to choose<\/h2>\n<p>Standard and Datacenter require a <strong>CAL<\/strong> (Client Access License) for each user or device connecting to the server, on top of the server license itself. CALs must match the server version or a newer one: CALs from an earlier version are not valid for Windows Server 2022.<\/p>\n<ul>\n<li><strong>User CAL<\/strong>: suits mobile employees who use several devices (office PC, laptop, tablet).<\/li>\n<li><strong>Device CAL<\/strong>: suits workstations shared between several people, for example in shifts.<\/li>\n<li><strong>RDS CAL<\/strong>: needed in addition for remote desktop sessions, as explained in our <a href=\"\/windows-server-rds\/\">Windows Server RDS guide<\/a>.<\/li>\n<\/ul>\n<p>Essentials requires none: its limits of 25 users and 50 devices are built into the product. CALs are separate from the server key and are not included with it.<\/p>\n<h2>Hyper-V virtualization: what the Standard edition really allows<\/h2>\n<p>A Standard license covering all cores grants the right to run <strong>two Windows Server virtual machines<\/strong>, plus the physical host as long as it only runs the Hyper-V role. Need four virtual machines? You stack a second full license on the same machine, in steps of two. Beyond six to eight virtual machines, Datacenter becomes the more economical choice and unlocks Storage Spaces Direct, software-defined networking and shielded virtual machines, which Standard lacks.<\/p>\n<p>Windows Server 2022 also brings AES-256 encryption for SMB and cluster traffic, TLS 1.3 enabled by default, nested virtualization on AMD processors and noticeably lighter Server Core container images.<\/p>\n<h2>Hardware, workstations and support timeline<\/h2>\n<p>Plan for a 64-bit 1.4 GHz processor with NX and DEP support, 2 GB of RAM with Desktop Experience (512 MB for Server Core) and 32 GB of disk at the bare minimum; in real life, aim considerably higher. Secured-core features require UEFI, Secure Boot, TPM 2.0 and hardware virtualization enabled.<\/p>\n<p>On the client side, PCs running <a href=\"\/product\/windows-11-pro\/\">Windows 11 Pro<\/a> ({prix:windows-11-pro}) join the domain without any special handling; the Home editions cannot. Windows 10 Pro ({prix:windows-10-pro}) remains an option for PCs that cannot run Windows 11, keeping in mind that Microsoft ended its standard support in October 2025. For a heavy-duty machine (CAD, rendering, large data sets), <a href=\"\/product\/windows-11-pro-for-workstations\/\">Windows 11 Pro for Workstations<\/a> at {prix:windows-11-pro-for-workstations} supports server-grade hardware.<\/p>\n<p>Finally, the calendar: Windows Server 2022 mainstream support ended on 13 October 2026, but security updates continue until <strong>14 October 2031<\/strong>, which leaves five more years of security fixes. Our keys come from genuine licenses resold within the European Union, a model confirmed by the Court of Justice of the EU in the UsedSoft ruling (case C-128\/11).<\/p>\n<h2>Ordering your Windows Server 2022 license<\/h2>\n<ol>\n<li>Add the license to your cart and pay by card, Apple Pay, Google Pay or Bancontact.<\/li>\n<li>Receive the product key by email within minutes, with the installation instructions.<\/li>\n<li>Install Windows Server 2022 from Microsoft&#8217;s official image, choosing the edition that matches your key.<\/li>\n<li>Enter the key during setup or afterwards: activation takes place on Microsoft&#8217;s official servers.<\/li>\n<\/ol>\n<p>You receive an invoice with VAT, and your purchase comes with lifetime replacement of a defective key.
