Windows Server 2025 1 User CAL

This Microsoft Windows Server 2025 User CAL is a client access license that grants one designated user access rights to Windows Server 2025 services on properly licensed server installations. It is used in Windows Server environments that license access by user rather than by device, so the CAL count is tied to users who connect to the server rather than to the number of PCs, thin clients, or mobile devices they use. This license does not include the Windows Server operating system or server core licensing; it should be aligned with the organization’s Windows Server 2025 licensing program and its chosen User CAL versus Device CAL model.
