Remote Desktop Services basics
What is RDS and why are RDS CALs required?
Remote Desktop Services, commonly called RDS and formerly known as Terminal Services, allows users to connect to a Windows Server environment and access remote desktops, published applications, and session-based workspaces. An RDS CAL is the Remote Desktop Services Client Access License required for users or devices that access an RDS deployment.
Simple licensing view
For Remote Desktop access, the server environment and the required RDS CALs are separate licensing parts.
What RDS does
RDS helps businesses provide remote access to Windows Server desktops, applications, and shared work environments. In older Windows Server environments, this type of remote access was commonly referred to as Terminal Services.Why CALs are needed
When users or devices connect to Remote Desktop Services, they need the correct Microsoft RDS CALs for that Windows Server RDS environment.How CALs are managed
In a standard RDS deployment, RDS CALs are installed and managed through the Remote Desktop Licensing role in Windows Server.What is separate
RDS CALs do not include the Windows Server operating system, application licenses, hosting, server setup, or other Microsoft licenses.
User CALs vs Device CALs
Choose whether access follows a user or a device
RDS CALs are purchased as either User CALs or Device CALs.
The right option depends on how users and computers connect to your Remote Desktop Services environment.
Simple rule
Choose User CALs when access follows people. Choose Device CALs when access follows shared or fixed machines.
Licensed by person
RDS User CALs
User CALs are usually best when the same named users need Remote Desktop access from multiple devices.
Best when:
- Named users connect from different devices
- Access is tied to employees or regular users
- The environment uses Active Directory
Important: User CALs require an Active Directory environment. If your server is in a Workgroup and you do not intend to use Active Directory, please choose Device CALs.
Licensed by endpoint
RDS Device CALs
Device CALs are usually best when Remote Desktop access is tied to shared computers, terminals, or fixed workstations.
Best when:
- Multiple people use the same workstation
- Access is tied to fixed devices or terminals
- The server is in a Workgroup environment
Workgroup setup? If your server is not joined to Active Directory, Device CALs are usually the safer and more practical choice.

Yes. Our licenses are supplied as standard Microsoft volume licenses for compliant use in supported environments. If your organization is currently going through, preparing for, or responding to a formal Microsoft audit or Software Asset Management (SAM) review, please contact us before purchasing so we can confirm the right license format for your setup and compliance requirements.
Can IT consultants or MSPs purchase RDS CALs for clients?

Do these CALs include downgrade rights for older server versions?
Yes. Higher-version RDS CALs include downgrade rights for earlier supported Windows Server RDS deployments. For example, Windows Server 2025 RDS CALs can be used with Windows Server 2025, 2022, 2019, and 2016 RDS environments. Older RDS CALs cannot be used with newer Windows Server versions.
Will 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.
Is there a time limit to activate the license after purchase?
No. There is no short activation deadline after purchase. You can keep the license details safely and activate the RDS CALs when you are ready to deploy them on a supported Windows Server RDS environment.
Do I own the license permanently?

Go to your order summary, choose the correct product, and pay any applicable price difference. Once the exchange is completed, the original license key is permanently blacklisted to prevent unauthorized use.
Can these CALs be transferred to a different server?
Yes. These RDS CALs can be moved to another server when you replace or upgrade your server hardware. To remain compliant, the original server must be fully decommissioned or wiped before the licenses are activated on the new deployment.
