How to Install RDS CALs on Windows Server 2025
A step-by-step guide to installing the Remote Desktop Licensing role, activating the server, and installing licenses.
Windows Server 2025 has been released; however, installing Remote Desktop Services (RDS) Client Access Licenses (CALs) follows a similar process to previous versions. The process involves two primary steps: installing the role and then activating the license server.
Prerequisites
Before you begin, ensure you have the following:
Step 1: Install the Remote Desktop Licensing Role
- Open Server Manager on your Windows Server.
- Click Manage > Add Roles and Features.
- Click Next on the "Before You Begin" screen.
- Select Role-based or feature-based installation and click Next.
- On the "Select destination server" page, choose the server you're using for this role from the server pool and click Next.
- Check the box for Remote Desktop Services on the "Select server roles" page, then click Next.
- Click Next again to skip the "Features" screen.
- On the "Remote Desktop Services" page, click Next.
- Select Remote Desktop Licensing and Remote Desktop Session Host from the list of role services. (Click Add Features if prompted).
- Click Next and then Install on the "Confirmation" page.
(The server may need to restart after the installation is complete).
Step 2: Activate the License Server and Install CALs
Once the role is installed, you can activate the server and add your licenses.
- Open Server Manager and navigate to Tools > Remote Desktop Services > Remote Desktop Licensing Manager.
- Right-click on the server name and select Activate Server.
- The Activate Server Wizard will open. Click Next.
- Select Automatic connection (recommended) and click Next.
- Fill in the required company information and click Next. (The server will contact Microsoft's clearinghouse).
- Once activation is successful, the wizard may prompt you to install licenses. If not, right-click the server and select Install Licenses.
- Click Next on the "Welcome to the Install Licenses Wizard" screen.
- Choose the License Program you purchased your CALs through (e.g., Retail Purchase, Select License, Other Agreement) and click Next.
- Enter your License Key or Agreement Number and click Next.
- Specify the Product Version, License Type (Per User or Per Device), and Quantity.
- Click Next. The server will contact Microsoft to install your CALs.
Your installed RDS CALs will now appear in the RD Licensing Manager.
⚠️ Important Next Step:
Installing the CALs is not enough. You must configure the server to use them.
