Buy a genuine Windows Server 2025 RDS User CAL pack and license your team for Remote Desktop Services on Windows Server 2025. Choose 5, 10, 20 or 50 users; the license key is delivered instantly by email and installed on your RD Licensing server, with no subscription to renew.

A Remote Desktop Services User CAL (Client Access License) lets one named person connect to remote desktops and RemoteApp programs from any number of devices. It suits office staff, remote workers and anyone who uses a laptop, a home PC and a phone. This page explains how User CALs work, what else you need, and how to install them.

Why Buy a Windows Server 2025 RDS User CAL?

Without RDS CALs, Remote Desktop Services runs only during a grace period of up to 120 days. After that, the RD Session Host stops accepting connections until licenses are installed.

Common reasons to buy User CALs include:

• Giving remote and hybrid staff access to company desktops and apps
• Publishing accounting or ERP software as RemoteApp programs
• Licensing users who work from a laptop, a home PC and a tablet
• Building a new RDS farm on Windows Server 2025
• Ending a grace period before connections are refused

If several staff share one computer on shifts, the Device CAL for Windows Server 2025 RDS may cost less.

RDS User CAL vs RDS Device CAL

Remote Desktop Services is licensed per user or per device. Pick the model that matches how people actually work:

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

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

What Else Do You Need for Remote Desktop Services?

An RDS User CAL is one part of a licensed RDS deployment. A complete setup includes:

• A licensed Windows Server, such as Windows Server 2025 Standard
• A Windows Server CAL for each user or device that accesses the server
• An RDS CAL for each user or device 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.

Windows Server 2025 RDS User CAL Compatibility

RDS CALs work with the same version of Windows Server and earlier versions. A Windows Server 2025 RDS User CAL can therefore cover users 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. To install 2025 CALs, the RD Licensing role must run on Windows Server 2025. Users connecting to a Windows Server 2025 session host need 2025 CALs; older CALs are not accepted there.

How Many Windows Server 2025 RDS User CALs Do You Need?

Count every person who will open a remote desktop session or RemoteApp program, including part-time staff, contractors and administrators who use RDS for daily work. Administrators who connect only to manage the server do not need an RDS CAL, because Windows Server includes two administrative sessions.

A few examples make the count easier:

• An office of 8 staff working from home: one 10-user pack
• A team of 15 using laptops and phones: a 10-user pack plus a 5-user pack
• An accounting firm of 45 users on RemoteApp: one 50-user pack

It is sensible to leave a little headroom for new starters, because an unlicensed user is a compliance gap even when the server still lets them connect. Per User CALs are not technically enforced by the license server, so keeping your own count accurate matters.

Who Should Buy Windows Server 2025 RDS User CALs?

This license is the right choice when you:

• Have more devices than people using remote desktops
• Support remote, hybrid or traveling staff
• Run RD Session Hosts on Windows Server 2025 or earlier
• Want a one-time purchase instead of a monthly subscription
• Need 5 to 50 users now, with room to add more packs later

Packs can be combined, so 30 users is simply a 20-user pack plus a 10-user pack.

How to Install Windows Server 2025 RDS User CALs

RDS CALs are installed on the RD Licensing server, not on each user’s PC:

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 User 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 User. 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

If a licensing mode mismatch remains, users will keep seeing grace period warnings. Ten minutes of checking here can save a morning of support calls.

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.
