Buy Microsoft RDS CALs for Windows Server.

Microsoft Remote Desktop Services CALs — formerly Terminal Services — for Windows Server 2025, 2022, 2019 and 2016. Every user or device connecting to your deployment needs one, and we help you choose the right version, CAL type and quantity.

Upgrade and downgrade flexibility

Buy for the newest server you plan to run — a newer CAL still covers older ones.

CAL version you buy Windows Server versions it covers
2025 Maximum flexibility Newest CAL version, and the only one that covers a 2025 deployment.
2025 2022 2019 2016
2022 Popular choice Fits most current estates, with room to fall back to 2019 or 2016.
2025 2022 2019 2016
2019 Established servers For settled 2019 environments that may still run some 2016 hosts.
2025 2022 2019 2016
2016 Legacy support Only where the deployment is fixed at Windows Server 2016.
2025 2022 2019 2016

Upgrading your server OS later? Buy the CAL version for the server you’re moving to — it covers your current one in the meantime, so you don’t repurchase after the upgrade. Rolling back to an older server? Your existing CALs already cover it; downgrade rights work automatically and need no exchange.

Will these RDS CALs work on my server?

Yes, as long as it runs a supported Windows Server with Remote Desktop Services turned on. It does not matter where the server runs.
