Server Licences, CALs and RDS CALs
Purchasing Windows Server requires more than selecting Standard or Datacenter edition. Organizations must also review server licensing, user or device Client Access Licences and any Remote Desktop Services access requirements.
Licensing should be based on the physical server, processor cores, virtualization requirements and the way users or devices access server services.
Key licensing components
- Windows Server 2025 Standard or Datacenter server licensing
- Core licensing based on the applicable physical-server requirements
- Windows Server User CALs or Device CALs for access
- Remote Desktop Services User CALs or Device CALs when users or devices access a graphical remote session
- Licensing for virtual machines and planned expansion
- Appropriate purchasing programme and proof of licensing
Information required for a licensing review
- Server model, processor count and physical cores
- Number of physical and virtual servers
- Number of users and devices accessing services
- Remote Desktop Services requirements
- Existing Windows Server licences and CALs
- Expected infrastructure growth
