Licensing Model Continuity: Core-Based Licensing Unchanged
Windows Server 2022 maintains the same core-based licensing model as Windows Server 2019. Both editions require licensing on a per-core basis, sold in 2-core or 16-core packages. There is no change to the fundamental licensing structure: the minimum purchase is 8 cores per physical CPU, and the minimum per server is 16 cores total.
List pricing for Windows Server 2022 is approximately $1,069 per 16-core Standard edition license and $6,155 per 16-core Datacenter edition license. These are vendor list prices; actual enterprise agreements typically negotiate significant discounts based on volume, existing Microsoft relationships, and Software Assurance commitment.
Client Access License (CAL) Requirements Remain
Client Access Licenses are still required for Windows Server 2022, regardless of edition. Organizations must license every user or device that accesses the server, using either User CALs or Device CALs. This requirement has not changed from Windows Server 2019 and is often the largest licensing cost beyond the server license itself.
The choice between User CALs and Device CALs depends on your environment: User CALs apply when the same user accesses multiple devices; Device CALs apply when multiple users share devices. Many organizations implement hybrid licensing to optimize costs across both user-based and device-based access patterns.
Key Licensing Changes in Windows Server 2022
Secured-Core Server Licensing
Windows Server 2022 introduces Secured-Core Server, a hardware and firmware security certification. This is not a separate licensing model; it simply means the server hardware meets higher security standards (UEFI Secure Boot, TPM 2.0, Measured Boot). If you purchase Secured-Core compatible hardware, there is no additional licensing cost, but the hardware cost is higher due to enhanced security components.
SMB Encryption: AES-256 by Default
Windows Server 2022 upgrades SMB (Server Message Block) encryption from AES-128 to AES-256 by default. This is a security enhancement with no licensing implications, but it may require updated network infrastructure and client machines to support the stronger encryption cipher. Plan for compatibility testing when upgrading from 2019 to 2022.
TLS 1.3 Default Enablement
TLS 1.3 is now enabled by default in Windows Server 2022, replacing TLS 1.2 as the preferred protocol. Again, this is a security feature with no direct licensing cost, but it may require updates to client applications and security appliances that intercept TLS traffic.
Azure Arc Integration and Hybrid Management
Windows Server 2022 includes enhanced Azure Arc integration for hybrid server management. Azure Arc itself is a separate service with its own pricing model, but there is no change to Windows Server licensing for Arc-managed servers. If you use Azure Arc for centralized management of on-premises Windows Server 2022 machines, you pay for Arc per server; the Windows Server license cost remains unchanged.
Windows Server 2022 Datacenter: Azure Edition
Microsoft introduced Windows Server 2022 Datacenter: Azure Edition, a cloud-specific variant designed for hyperscaler deployments. Azure Edition includes Hotpatch, which allows live kernel patching without server restart, and is optimized for Azure virtual machines.
Licensing for Azure Edition differs from standard editions: it is typically sold through Azure subscription models and pay-as-you-go pricing, not perpetual licenses. If you deploy Windows Server on Azure VMs, Azure Edition is often the cost-effective choice. For on-premises or non-Azure cloud, standard Datacenter edition is appropriate.
Azure Hybrid Benefit for Windows Server
If your organization has Software Assurance (SA) on Windows Server licenses, you can use Azure Hybrid Benefit to deploy those licenses on Azure VMs at no additional cost. This benefit has been available since Windows Server 2016, but it's critical to understand the scope for 2022 deployments:
- Requires active Software Assurance on your licensing agreement.
- Allows you to run Windows Server 2022 Standard or Datacenter on Azure VMs with no additional Azure compute charges (you still pay for storage, networking, and other services).
- The on-premises license remains usable; Azure Hybrid Benefit grants Azure rights only, not a transfer of the on-premises license.
- Requires proper tracking and attestation to demonstrate SA coverage.
Forward Compatibility and License Enforcement
A critical licensing point: Windows Server 2019 Standard or Datacenter licenses cannot be used to run Windows Server 2022 on the same physical server without an upgrade license. This is a common source of audit findings. If you currently run 2019 and want to deploy 2022 on the same hardware, you must either upgrade the licenses or decommission the 2019 deployment.
Upgrade licensing from 2019 to 2022 is available with Software Assurance. Without SA, you must purchase full 2022 licenses. This is an important cost factor in your deployment roadmap.
Software Assurance Requirements
Software Assurance remains important for Windows Server 2022, though it is not mandatory for basic licensing. However, SA is required for several capabilities:
- Free upgrades: Upgrading from 2019 to 2022 at no license cost requires SA.
- Azure Hybrid Benefit: Using on-premises licenses on Azure VMs requires SA.
- License mobility: Transferring licenses between VMs (if using Datacenter edition) requires SA documentation.
- Extended Security Updates: Support beyond the mainstream support window requires SA or separate ESU licenses.
Upcoming Windows Server 2025 and Beyond
Windows Server 2025 is now available in preview and will be released shortly. Organizations planning 2022 deployments should consider whether to wait for 2025 or deploy 2022 now. 2022 has matured support and a longer service lifetime, making it suitable for long-term deployments. 2025 will offer newer security and hybrid features, but with shorter remaining support lifecycles.
Licensing Strategy and Cost Optimization
Negotiating Windows Server in Your EA
Windows Server licensing is typically bundled into Microsoft Enterprise Agreements alongside other products. Key negotiation points include:
- Software Assurance scope: Ensure your EA explicitly covers Windows Server SA benefits.
- Hybrid benefit eligibility: Confirm that Azure consumption discounts apply to your Windows Server licenses.
- CAL allocation: Negotiate CAL costs based on your user/device distribution.
- Renewal terms: Consider 3-year commitments for discounts, or annual renewals if your infrastructure is transitioning.
Cost Comparison: 2019 vs 2022
Total cost of ownership includes license costs, Azure Hybrid Benefit value (if applicable), and support/security update costs. A 100-server 2022 Datacenter deployment with SA typically costs less than 2019 deployment when Azure Hybrid Benefit is factored in, because the upfront license cost is amortized over longer service periods and cloud consumption discounts apply earlier.

Redress Compliance advises on Microsoft infrastructure licensing and EA optimization.Key Takeaways
Windows Server 2022 licensing uses the same core-based, CAL-required model as 2019, but new security features, Azure Arc integration, and Hotpatch capabilities open new deployment options. Organizations should focus on Software Assurance coverage to enable free upgrades, Azure Hybrid Benefit eligibility, and long-term support. Ensure your EA renewal or new agreement explicitly authorizes 2022 deployments and clarifies upgrade paths from 2019. Plan for compatibility testing of the enhanced encryption and TLS defaults before large-scale 2022 rollouts.
