Microsoft Windows Server 2025 – 1 Device Client Access License (CAL) grants a specific device the legal right to access services provided by Windows Server 2025. This licensing model allows multiple users to connect to Windows Server from a single licensed device, making it a cost-effective solution for environments where workstations are shared.

Device CALs are required for each device that accesses Windows Server services such as file sharing, printing, authentication, and application hosting within a Windows Server network environment.

This licensing option is ideal for organizations with shared workstations or shift-based work environments where multiple users utilize the same computer to access network resources.
