02Which Windows Server versions are these 2025 RDS CALs compatible with?
Higher-version RDS CALs include downgrade rights for earlier supported Windows Server RDS deployments. Windows Server 2025 RDS CALs can be used with Windows Server 2025, 2022, 2019 and 2016 RDS deployments.
03Is the Windows Server 2025 operating system included?
No. An RDS CAL is an access license for Remote Desktop Services and does not include the Windows Server 2025 operating system itself. The Windows Server 2025 needs to be licensed separately.
04Will these licenses expire or require renewal?
No. These are perpetual RDS CALs and do not require monthly or annual renewal. Once purchased, the licenses remain valid for the supported lifetime of the Windows Server RDS version they are purchased for, including eligible downgrade use.
05Can I use these RDS CALs in my country?
Yes. RDS CALs are not region-locked — they can be deployed on Windows Servers located anywhere in the world, whether on-premises or on dedicated cloud servers.
06Can I add more RDS CALs in the future?
Yes. Additional RDS CALs can be purchased and added to your server in the future.
