Windows Server 2025 RDS 50 Device CAL is a bundle of Remote Desktop Services licenses that allows 50 devices to legally use Remote Desktop on Windows Server 2025. RDS CAL licenses are required IN ADDITION TO standard CAL licenses — every user or device connecting through Remote Desktop needs both a CAL and an RDS CAL. Buying the 50-pack of RDS CALs from Licensier means a cheap price, substantial savings compared to Microsoft retail pricing, and full licensing compliance for your remote access infrastructure.
What is an RDS CAL?
RDS Client Access License — the key to legal access
An RDS CAL (Remote Desktop Services Client Access License) is a special Microsoft license required for the legal use of Remote Desktop Services on Windows Server. It is an additional license on top of the standard CAL. A Device CAL is assigned to one device, and any number of users can use that device. RDS CALs are essential in every environment where employees connect to the server via Remote Desktop Protocol (RDP) — remote work, access to server applications, virtual desktops (VDI), or thin-client terminals.

Frequently asked questions
What is an RDS Device CAL?
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.
What is the difference between User CAL and Device CAL?
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.
Is RDS CAL enough on its own?
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.
What is Remote Desktop Services used for?
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.
Do RDS CAL 2025 licenses work with newer servers?
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.
What are the risks of not having CAL licenses?
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.
Can I transfer a Device CAL to another device?
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.
Are the licenses original?
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.
