Join nowIn modern hybrid workplaces, the ability to deliver line-of-business applications and full desktops securely to any device is not just an IT convenience—it is a strategic necessity. The Microsoft Windows Server 2016 Remote Desktop Services (RDS) User Client Access License (CAL) is the licensing key that transforms a standard Windows Server deployment into a powerful, centralised application and desktop delivery platform. This 10-pack of perpetual User CALs authorises ten named users in your organisation to access Remote Desktop Session Host (RDSH) sessions, RemoteApp programs, or Virtual Desktop Infrastructure (VDI) from any device they own—a company laptop, a home PC, or even a tablet.
Unlike Device CALs that lock a license to a specific piece of hardware, User CALs follow the individual. This makes them the ideal choice for organisations with mobile employees, shift workers, or Bring-Your-Own-Device (BYOD) policies where a single user needs to connect from multiple devices throughout their workday. By purchasing this license pack, you are investing in a perpetual, non-expiring right to use RDS functionality on Windows Server 2016, with full down-version rights to earlier server operating systems. It is the foundational component for secure, server-based computing that keeps sensitive data off endpoint devices and firmly within the controlled confines of your data centre or private cloud.
When you complete your purchase of the Windows Server 2016 RDS 10 User CAL pack from Lizensa, you are acquiring a genuine, verified Microsoft license right, not just a string of characters. Your order confirmation and delivery email will contain everything you need to become compliant and operational. Specifically, you receive a perpetual license activation key that does not expire. This is a volume-license style key, typically provided as a Multiple Activation Key (MAK) or designed for your internal Key Management Service (KMS), depending on the specific fulfilment.
Alongside the license key, you receive a direct download link to the official Microsoft Volume Licensing Service Center (VLSC) or Microsoft 365 admin centre portal, where you can obtain the necessary RDS license server activation components. We include a detailed, step-by-step activation guide written in clear international English to walk you through installing the RDS role, activating the license server, and installing your new User CALs. A full VAT-compliant invoice is provided, which is essential for your company's financial records and software asset management audits. This license is a permanent, one-time purchase, not a recurring subscription, and is valid for use across all 27 EU member states.
Understanding the distinction between User and Device CALs is critical for cost-effective compliance. A Windows Server 2016 RDS User CAL (this product) licenses a single named user to access RDS functionality from any device. This is the optimal choice if your employees are mobile, work from multiple locations, or use a mix of company-provided and personal devices (BYOD). For example, a salesperson who accesses a CRM via RemoteApp from their office desktop, their laptop at home, and their tablet while travelling requires only one User CAL.
Conversely, a Windows Server 2016 RDS Device CAL licenses a single physical device to be used by any number of users to access RDS. This model is more economical for shift-work environments where multiple employees share the same endpoint, such as a factory floor kiosk, a hospital nursing station terminal, or a call centre desk. If three nurses share a single thin client on a rotating shift, you only need one Device CAL for that thin client, rather than three User CALs. Your choice should be driven by whether the user or the device is the constant in your access scenario. This product provides the User CAL model, offering maximum flexibility for the modern, mobile workforce.
This product is a license key and does not have traditional hardware requirements like RAM or processor specifications. However, it is imperative to understand the environmental prerequisites for its use. This RDS User CAL pack is specifically designed for Windows Server 2016. It requires an existing, properly licensed Windows Server 2016 environment with the Remote Desktop Services role installed and configured.
A critical licensing prerequisite is that every user accessing RDS must also be licensed with a standard Windows Server 2016 CAL. The RDS CAL is an additive license; it does not replace the standard CAL. You must have both a Windows Server CAL and an RDS CAL for each connecting user. The RDS license server can be activated on a physical or virtual instance of Windows Server. This license supports all standard RDS deployment scenarios, including session-based desktops, RemoteApp, and VDI. It is compatible with connections made via Remote Desktop Gateway, Remote Desktop Web Access, and direct RDP client connections. The RDS client software is natively available for Windows devices and is not supported on macOS or Linux as a licensed endpoint for this server technology. The license key itself and the activation process support multiple languages, including English, German, French, Spanish, Italian, Dutch, Polish, Portuguese, and Japanese. For any specific server hardware requirements to run the RDS role efficiently, you should consult the official Microsoft Windows Server 2016 documentation.
The path to activation is a digital-first, rapid process designed to get your IT team moving without delay. Once your payment is securely processed, you will receive an email from Lizensa containing your unique license key, a direct download link for the official Microsoft software, and a comprehensive activation guide. Our average delivery time is under sixty seconds, ensuring you have your license when you need it.
Activation involves a two-stage process on your Windows Server 2016 network. First, you must install the Remote Desktop Licensing role on a server within your domain and activate the RDS License Server using the key we provide. This process connects to Microsoft's clearinghouse to validate and activate your license server. Second, you install your 10 User CALs onto that activated license server. Our guide provides clear, screenshot-led instructions for both the automatic online activation and, if your server lacks internet access, the manual telephone or web-based activation methods. This is a perpetual license, meaning you can reinstall and reactivate the license server on the same or replacement hardware as needed, in accordance with Microsoft's volume licensing terms. Should you encounter any validation errors, our free multilingual technical support team is ready to assist.

As a European company, we provide all the consumer protections guaranteed under EU law, including a straightforward 14-day right of withdrawal.

This is a perpetual, one-time purchase. The Windows Server 2016 RDS User CALs you acquire do not expire and grant a permanent right to use the Remote Desktop Services functionality on Windows Server 2016, with down-version rights to earlier server versions. You will not be charged a recurring fee.
A standard Windows Server CAL grants a user or device the right to access a Windows Server for basic network services like file sharing, printing, or Active Directory authentication. An RDS CAL is an additional, separate license required specifically when a user accesses a full remote desktop, a published RemoteApp, or a VDI desktop. You need both a standard CAL and an RDS CAL for each user connecting via Remote Desktop Services.
Our delivery is fully automated and near-instant. On average, the email containing your license key, download links, and activation guide arrives in your inbox within 60 seconds of your payment being successfully processed by our secure payment gateway.

We offer a 14-day right of withdrawal in full compliance with EU consumer protection law. If you have not activated or used the license, you can request a full refund within 14 days of your purchase.
No. Microsoft's licensing terms for RDS User CALs typically require that the licensed user is an employee or a similarly qualified member of your organisation. For providing access to external third parties, you would need to explore a Service Provider License Agreement (SPLA) or a specific External Connector license.
These CALs provide the right to connect to the Windows Server desktop or published applications. Licensing Microsoft Office, such as Microsoft 365 Apps, to run on an RDS server is a separate consideration and requires specific per-user subscription licenses (like Microsoft 365 E3/E5) or volume license copies with Software Assurance. This RDS CAL does not include any Office licensing rights.
