Windows Server RDS CALs & Remote Desktop Licenses

Browse our collection of Windows Server RDS CALs for compatible Microsoft Remote Desktop Services environments. These Remote Desktop Services Client Access Licenses are designed for organisations and IT environments that need to provide authorised users or devices with access to Windows Server Remote Desktop Services.

Our collection includes RDS User CALs and RDS Device CALs for multiple Windows Server generations. Before purchasing, carefully check your existing Windows Server version, the RDS licensing model you require, and the number of users or devices that need access.

What Is a Windows Server RDS CAL?

A Windows Server RDS CAL, or Remote Desktop Services Client Access License, is an access licence used in eligible Remote Desktop Services deployments.

Depending on the product and licensing requirements, RDS CALs may be required in addition to:

• A Windows Server licence

• Windows Server CALs

• Remote Desktop Services infrastructure

• Other applicable Microsoft licensing requirements

An RDS CAL does not replace the Windows Server operating system licence. Always check the licensing requirements for your specific environment before purchase.

RDS User CAL vs RDS Device CAL

Choosing between an RDS User CAL and an RDS Device CAL depends on how people access your Remote Desktop Services environment.

RDS User CAL is assigned to a specific user and may be suitable when one person needs access from multiple compatible devices.

RDS Device CAL is assigned to a specific device and may be suitable when multiple users access the Remote Desktop Services environment from the same shared device.

For example, a User CAL may suit an employee who works from an office computer, home computer and laptop. A Device CAL may be suitable for a shared workstation used by multiple staff members across different shifts.

Choose the licensing model that best matches your organisation's access requirements and always review the applicable licence terms.
