Windows Server 2025 Remote Desktop Services 50 Device CALs license RDS access by endpoint rather than by named person. This makes them a practical fit for shared terminals, call-centre stations, reception computers and shift-based workplaces where many users rotate through the same devices.
Device CALs are assigned to endpoints and work well when several employees share each licensed machine. User CALs are assigned to people and are generally better when each person connects from multiple PCs or mobile devices. For that pattern, compare Windows Server 2025 RDS 50 User CALs.
This is an RDS access-license pack. It does not include Windows Server 2025, ordinary Windows Server CALs, client operating systems or a configured Remote Desktop deployment. A compatible RD Licensing server must issue the CALs, and the RD Session Hosts must use Per Device licensing mode.
Microsoft permits Windows Server 2025 RDS CALs to access compatible Windows Server 2025 or earlier Session Hosts. Earlier RDS CAL generations cannot be used to license a 2025 Session Host. The license server must also be new enough to install and issue the CAL pack.
Count every connecting endpoint that requires RDS access, including thin clients, shared PCs and dedicated terminals. Compare that device count with the 50-CAL quantity and document any separate Windows Server CAL requirements before purchasing.
