Remote Desktop Services, previously known as Terminal Services, requires RDS CALs for every user or device connecting to a Windows Server Remote Desktop Services deployment.

Choose by server version

Choose the right Windows Server RDS CAL version

Match your RDS CAL version to the Windows Server version in your Remote Desktop Services deployment. Newer CALs cover older servers through downgrade rights — older CALs don't work on newer servers.
View all RDS CALs
Version rule Choose an RDS CAL version that's the same as or newer than the Windows Server version receiving Remote Desktop Services connections. Newer RDS CALs can usually be used with earlier supported server versions through downgrade rights, but older RDS CALs should not be used for newer Windows Server deployments.
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, lets users 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.
The service

What RDS does

RDS lets businesses provide remote access to Windows Server desktops, applications, and shared work environments. In older Windows Server environments, this remote access was commonly called Terminal Services.
The requirement

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.
The tooling

How CALs are managed

In a standard RDS deployment, RDS CALs are installed and managed through the Remote Desktop Licensing role in Windows Server.
The boundary

What is separate

RDS CALs do not include the Windows Server operating system, application licenses, hosting, server setup, or other Microsoft licenses.
License note RDS CALs are access licenses. They help license Remote Desktop Services access, but they don't replace the Windows Server operating system license or any required application licensing.
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 don't intend to use Active Directory, 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 isn't joined to Active Directory, Device CALs are usually the safer and more practical choice.

Answers for IT buyers, administrators, consultants, MSPs, and procurement teams reviewing RDS CAL pricing, deployment use, downgrade rights, and exchange options before purchase.
Review before checkout Use these answers to confirm common purchase details before moving to the shop page or contacting support.
How does your pricing compare to traditional CSP or procurement channels?
Traditional CSP and procurement channels often include pricing floors, distributor layers, reseller margins, and longer purchasing workflows. RDS CAL Store operates as an independent volume licensing specialist, allowing us to source Microsoft RDS CALs at scale and price them more efficiently.
What about a Microsoft audit or SAM review?
If your organization is going through, preparing for, or responding to a Microsoft audit or Software Asset Management (SAM) review, contact us before purchasing so we can recommend the right license format for your setup and compliance requirements.
Can IT consultants or MSPs purchase RDS CALs for clients?
Yes. IT consultants, MSPs, and system integrators can purchase RDS CALs for client deployments. Please mention the correct customer or client details in the order details or order notes when placing the order.
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're ready to deploy them on a supported Windows Server RDS environment.
Are these licenses region-restricted?
No. Our RDS CALs are approved for worldwide deployment and are not region-restricted. You can install and deploy these licenses on servers located anywhere in the world.
Can I use these licenses on cloud platforms?
Yes. You can use these RDS CALs for Windows Server Remote Desktop Services deployments on cloud environments such as AWS, Google Cloud Platform (GCP), Microsoft Azure, third-party cloud hosting providers, dedicated servers, or on-premises servers, as long as the server environment supports standard RDS CAL installation and activation.
Is the Windows Server operating system included?
No. An RDS CAL is an access license for Remote Desktop Services. It does not include the Windows Server operating system.
Can I add the CALs to VLSC?
Contact us before purchase if you wish to add the CALs to VLSC.
What if I order the wrong CAL type or server version?
If you purchase the wrong server version or need to switch between User and Device CALs, you can exchange eligible unactivated licenses from your account dashboard within 60 days of purchase. 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.
