Device CAL for Windows Server 2025 Remote Desktop Services (RDS)

Buy a genuine Device CAL for Windows Server 2025 Remote Desktop Services and license shared computers for remote desktop access. Choose 5, 10, 20 or 50 devices; the license key is delivered instantly by email and installed on your RD Licensing server, with no subscription to renew.

An RDS Device CAL (Client Access License) lets one physical device connect to remote desktops and RemoteApp programs, no matter how many people use it. It suits call centers, factories, clinics, classrooms and any workplace where staff share computers on shifts. This page explains how Device CALs work, what else you need, and how to install them.

Why Buy a Device CAL for Windows Server 2025?

Remote Desktop Services needs a CAL for every connecting user or device once the grace period of up to 120 days ends. After that, the RD Session Host refuses connections from unlicensed devices.

Common reasons to buy the Device CAL for Windows Server 2025 include:

• Licensing shared PCs used by several shifts each day
• Equipping thin clients in warehouses, factories or retail stores
• Covering reception, nursing station or classroom computers
• Building a new RDS farm on Windows Server 2025
• Ending a grace period before connections are refused

If each person uses several devices, such as a laptop and a phone, the Windows Server 2025 RDS User CAL is the better fit.

RDS Device CAL vs RDS User CAL

Remote Desktop Services is licensed per device or per user. Pick the model that matches how your workplace runs:

Question	Device CAL	User CAL
What is licensed	One physical device	One named person
Number of users covered	Unlimited on that device	One
Number of devices covered	One	Unlimited for that user
Best fit	Shared PCs, shifts and thin clients	Remote, hybrid and mobile staff
Tracking	Issued and tracked by the license server	Reported through Active Directory

A simple rule: count people and count devices, then license whichever number is smaller.

What Else Do You Need for Remote Desktop Services?

The Device CAL for Windows Server 2025 is one part of a licensed RDS deployment. A complete setup includes:

• A licensed Windows Server, such as Windows Server 2025 Standard or Datacenter
• A Windows Server CAL for each device or user that accesses the server
• An RDS CAL for each device or user that uses remote desktop sessions
• An RD Licensing server running Windows Server 2025

The Windows Server CAL and the RDS CAL are separate licenses. Microsoft’s RDS client access license documentation explains the rules in detail.

Device CAL for Windows Server 2025 Compatibility

RDS CALs work with the same version of Windows Server and earlier versions. A Device CAL for Windows Server 2025 can therefore cover devices on 2025, 2022, 2019 and 2016 RD Session Hosts.

The license server must run the same or a newer version than the CALs it holds, so the RD Licensing role must run on Windows Server 2025. Devices connecting to a Windows Server 2025 session host need 2025 CALs; older CALs are not accepted there.

How Many Device CALs Do You Need?

Count every physical device that opens a remote desktop session or RemoteApp program, including thin clients, shared PCs and kiosk terminals. The number of people using each device does not matter.

A few examples make the count easier:

• A call center with 18 desks used across three shifts: a 10-device pack plus two 5-device packs
• A clinic with 9 shared nursing station PCs: one 10-device pack
• A warehouse with 45 thin clients: one 50-device pack

The license server issues a Device CAL for Windows Server 2025 the first time each device connects. Replacing hardware frequently can use up CALs faster than expected, though Microsoft lets expired device licenses return to the pool after a set period.

Who Should Buy the Device CAL for Windows Server 2025?

This license is the right choice when you:

• Have more people than devices using remote desktops
• Run shift work on shared computers or thin clients
• Run RD Session Hosts on Windows Server 2025 or earlier
• Want licenses that the server tracks automatically
• Prefer a one-time purchase instead of a monthly subscription

Packs can be combined, so 25 devices is simply a 20-device pack plus a 5-device pack.

How to Install Device CALs for Windows Server 2025

RDS CALs are installed on the RD Licensing server, not on each client device:

1. Install the Remote Desktop Licensing role on a Windows Server 2025 server.
2. Open RD Licensing Manager, right-click the server and select Activate Server.
3. Right-click the server again and select Install Licenses.
4. Choose the license program shown in your Bcdkey delivery email.
5. Enter the license key, select Windows Server 2025 and the Per Device CAL type, and enter the quantity.
6. Finish the wizard and confirm the licenses appear in RD Licensing Manager.

Next, set the licensing mode to Per Device. In Server Manager, open Remote Desktop Services > Overview > Tasks > Edit Deployment Properties > RD Licensing. For servers outside a deployment, use the Group Policy setting below.

Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Licensing

A licensing mode that does not match the installed CALs is the most common cause of grace period warnings.

Delivery, Order Tracking and Support

Your license key is sent by email, typically instantly after payment, and is also saved in My Account. You can follow any order with Track Order.

If installation does not complete, open a support ticket with a screenshot of the RD Licensing Manager message.
