CAL RDS (Remote Desktop)

THE CAL RDS Client Access Licenses (CALs) authorize Remote Desktop connections to a Windows server. Here you will find packs of 50 User CALs and 50 Device CALs for Windows Server 2019, 2022, and 2025.

User CAL or Device CAL?

There User CAL is assigned to one person, who can log in from any device: this is the right choice for mobile employees or those working across multiple workstations. Device CAL is assigned to a device, usable by several people: it is suitable for shared workstations and working in successive shifts.

A CAL does not replace the server license

The CALs are coming in addition of the Windows Server license. They must be installed on the Remote Desktop Services Licensing Manager and then activated. Our guide Activate the RDS license server details the procedure.

Compatibility

The CAL version must match or be newer than the server version. See all our Windows Server licenses.
