If you're setting up Remote Desktop Services for a Windows Server environment, you need the right Client Access License pack - and the two 50-license options on the table come from different Server generations and use different CAL models. One is a Windows Server 2025 RDS 50 Device CAL pack priced at USD 289.00, and the other is a Windows Server 2019 RDS 50 User CAL pack priced at USD 159.55. The price difference is significant, but the real question is which CAL type and license format line up with how your team connects.
Quick verdict
Pick the Windows Server 2025 RDS 50 Device CALs if you're running Windows Server 2025 and want a 50-device license in a Product Key Card format with a lifetime license. Pick the Windows Server 2019 RDS 50 User CAL if you're on Windows Server 2019 and want a 50-user retail license at the lower listed price.
Comparison at a glance
| Product | Listed price | CAL type | License format | Relative price |
|---|---|---|---|---|
| Microsoft Windows Server 2025 RDS 50 Device CALs | USD 289.00 | Device | Product Key Card | |
| Microsoft Windows Server 2019 RDS 50 User CAL | USD 159.55 | User | Retail |
Both packs cover 50 CALs for Remote Desktop Services, and both are Brand New. The 2025 pack is a Product Key Card, while the 2019 pack comes as a retail license pack. The 2019 pack uses online activation with an internet connection.
Where each product wins
- Windows Server 2025 RDS 50 Device CALs wins on the Server 2025 edition, the Device CAL licensing model, and the included lifetime license.
- Windows Server 2019 RDS 50 User CAL wins on the lower listed price and the User CAL licensing model, and it comes in a retail format pack.
Product notes
Microsoft Windows Server 2025 RDS 50 Device CALs
If your environment relies on shared workstations, terminals, or devices that multiple people use, the Device CAL model is designed to license each device rather than each user. This is a Brand New Microsoft Product Key Card with a lifetime license, and it comes with an official holographic Certificate of Authenticity (CoA) and product key. The format is Product Key Card, and language support is English and Multilingual. If your team is already standardized on Windows Server 2025, this pack matches that generation. The main drawback is the higher listed price compared to the 2019 pack, so it makes sense only when you specifically need Device CALs and want to align with Windows Server 2025.
Microsoft Windows Server 2019 RDS 50 User CAL
This is a Brand New retail license from the United States, providing 50 user CALs for Remote Desktop access. It is not a PKC license for activating Windows Server itself, so treat it as the CAL component of your licensing. Activation requires an internet connection. The biggest plus is the lower listed price compared to the 2025 pack, making it an easier choice if you're on Windows Server 2019 and user-based licensing fits your access pattern. For environments where each user connects from multiple devices, a user CAL can be a practical fit. The limitation to keep in mind is that this is a Server 2019 CAL pack, so it may not be the right alignment if you're planning a Windows Server 2025 deployment.
Final choice by use case
- Choose the 2025 Device CAL pack if you're on Windows Server 2025, need device-based Remote Desktop access, and prefer the Product Key Card format with a lifetime license.
- Choose the 2019 User CAL pack if you're on Windows Server 2019, need user-based access, and want the lower listed price.
