Windows Server Licenses — 2025, 2022 & 2019

US Trusted Tech offers Windows Server licenses for organizations, IT administrators, and businesses in the United States. This collection covers Windows Server 2025, Windows Server 2022, and Windows Server 2019 in Standard and Datacenter editions, along with Remote Desktop Services (RDS) CALs and Client Access Licenses (CALs).

Windows Server licensing is more complex than consumer Windows licensing. Before purchasing, review the edition, core count, and CAL requirements for your specific environment. Each product listing on ustrustedtech.com includes specifications to help you select the right license.

Windows Server 2025

Windows Server 2025 is Microsoft's current server platform, introducing improvements in security, hybrid cloud integration, and performance over previous versions. Key additions include SMB over QUIC, improved Active Directory features, and enhanced support for Azure Arc hybrid management.

Windows Server 2025 Standard is suited for physical or minimally virtualized environments. It includes rights to run up to two Hyper-V virtual machines per licensed server when all physical cores are licensed.

Windows Server 2025 Datacenter is designed for highly virtualized and cloud environments. It provides unlimited Hyper-V VM rights on the licensed server, making it the appropriate choice for data centers running large numbers of virtual machines.

• Browse the Windows Server 2025 Standard – 16 Core License for Standard edition specifications.
• See the Windows Server 2025 Datacenter 16-Core License for Datacenter edition details and VM rights.

Windows Server 2022

Windows Server 2022 remains widely deployed in enterprise and SMB environments. It introduced Secured-core server capabilities, TLS 1.3 by default, and improved Azure hybrid integration. Organizations already running Server 2022 infrastructure may find it a cost-effective choice compared to upgrading to 2025.

Standard and Datacenter editions follow the same core-based licensing model as Server 2025. Review the Windows Server 2022 Standard – 16 Core License listing for edition details, core coverage, and CAL requirements.

Windows Server 2019

Windows Server 2019 is still in mainstream support and remains a stable choice for organizations that have not yet migrated to newer versions. It supports Hyper-V, Storage Spaces Direct, Software-Defined Networking, and Windows Containers.

Available editions include Standard and Datacenter. Check the Windows Server 2019 Standard – 24 Core License and the Windows Server 2019 Datacenter – 16 Core License listings for specifications and licensing details.

CALs & RDS Licenses

A Client Access License (CAL) is required for every user or device that accesses a Windows Server. CALs are not included with the server license and must be purchased separately. You can choose between User CALs (licensed per person) or Device CALs (licensed per device), depending on your environment.

Remote Desktop Services (RDS) CALs are required in addition to standard Windows Server CALs when users connect to the server through Remote Desktop Services. RDS CALs must match the version of Windows Server being accessed.

• See the Windows Server 2025 RDS CAL License for RDS per-user licensing on Server 2025.
• See the Windows Server 2022 Remote Desktop 10 User CAL for RDS licensing on Server 2022 environments.

Understanding Windows Server Licensing

Windows Server uses a core-based licensing model. Every physical server must have all its cores licensed, with a minimum of 16 cores per server (8 cores per processor, minimum 2 processors). Core licenses are sold in packs — review each product listing for the core count covered.

Edition comparison at a glance:

• Standard — suitable for physical servers or environments with limited virtualization (up to 2 Hyper-V VMs per license)
• Datacenter — suitable for highly virtualized environments with unlimited Hyper-V VM rights per licensed server

CAL requirements apply regardless of edition. Every user or device accessing the server needs the appropriate CAL. Consult your IT administrator or licensing specialist to confirm the correct number of CALs for your environment before purchasing.

Which Windows Server License Is Right for You?

Small businesses
Windows Server 2022 or 2025 Standard with the appropriate number of User or Device CALs. Standard edition covers most small business workloads including file sharing, Active Directory, and print services.

Mid-size organizations
Windows Server 2025 Standard or Datacenter depending on virtualization requirements. Add RDS CALs if users need remote desktop access to the server.

Data centers and enterprise environments
Windows Server 2025 Datacenter for unlimited VM rights. Pair with the appropriate CALs and RDS CALs based on user and device counts.

Organizations on existing Server 2019 or 2022 infrastructure
Continuing with the current version may be appropriate if the environment is stable and a migration is not yet planned. Review the product listings for available editions and core counts.
