Windows Server 2025 RDS 50 Devices

An RDS Device CAL (Remote Desktop Services Client Access License) is a Microsoft license that authorises a device to legally access Remote Desktop Services on a Windows Server 2025 server. A Device CAL is assigned to a device, and any number of users can use that device. Without the correct number of CAL licenses, using the server violates Microsoft's licensing terms.

A User CAL is assigned to a user and allows that user to connect to the server from any number of devices. A Device CAL is assigned to a device, and any number of users can use that device. User CAL is better for mobile employees. Device CAL is better for shared workstations and shift-based environments.

No. RDS CAL is an additional license required IN ADDITION TO the standard Windows Server CAL. Every user or device connecting through Remote Desktop needs both: (1) a standard Windows Server 2025 CAL and (2) a Windows Server 2025 RDS CAL. Both licenses are essential for full licensing compliance.

RDS (Remote Desktop Services) is a Microsoft technology that allows users to connect remotely to a server and use its resources as if they were sitting directly in front of it. Typical use cases include remote work, virtual desktops (VDI), publishing server applications for users, thin-client terminals in companies, and centralised IT management.

RDS CAL licenses for Windows Server 2025 are backward compatible, which means they work with Windows Server 2025 and earlier versions. They are not compatible with newer server versions. If you are planning a server upgrade, you should include the cost of new CAL licenses that match the target server version.

Using Windows Server without the required number of RDS CAL licenses is a breach of Microsoft's licensing terms. During an audit, this may result in financial penalties, the need to buy the missing licenses at full list price, and potential legal issues. Microsoft licensing audits are becoming increasingly common, so it is wise to secure compliance in advance.

Yes, a Device CAL can be transferred to another device, but not more often than once every 90 days. The exception is hardware failure — in that case, the transfer can be made immediately. The update only requires changing the assignment in the license management tool.

Yes, all licenses from Licensier are original Microsoft products with official activation keys. Every purchase is documented with a VAT invoice, which provides additional proof of legality during a licensing audit. The keys are verified by Microsoft licensing systems.
