Windows Server 2025 RDS 50 Device CALs
Windows Server 2025 RDS 50 Device CALs: a pack of 50 Remote Desktop Services client access licenses (RDS CALs) for Windows Server 2025, as Device CALs. Each one covers one device, whoever uses it.
Right after your payment is confirmed, we email you a secure link to your license, and your invoice comes with the order. Lifetime warranty on the server where you activate it. Only reveal your license when you are ready to install it.
What is an RDS CAL?
A Remote Desktop Services client access license (RDS CAL) lets a person or a device connect to a Remote Desktop session host running Windows Server. RDS CALs are separate products from Windows Server, sold in packs of 50. Microsoft’s licensing terms say which users and devices need an RDS CAL: check them for your setup.
User CAL or Device CAL?
| User CAL | Device CAL | |
| Covers | One person, from any device | One device, whoever uses it |
|---|---|---|
| A good fit when | Each person has their own devices | Several people share the same computers, for example in shifts |
Both examples come from Microsoft’s guidance: License Remote Desktop Services with Client Access Licenses (CALs).
How many packs do you need?
Each pack has 50. Count the people (User CALs) or the devices (Device CALs) that will connect to your session hosts: for example, 120 people need three packs. Buying several packs? Request a quote.
Which Windows Server version does it work with?
An RDS CAL pack works with its own Windows Server version or an earlier one, never a later one.

Questions about RDS CALs
Is the Windows Server 2025 RDS 50 Device CALs pack a Windows Server license?
No. RDS CALs are separate products from Windows Server, sold in packs of 50. The Windows Server edition you run them on is a separate product too: see Windows Server license keys.
What is the difference between User CALs and Device CALs?
A User CAL covers one person, from any device. A Device CAL covers one device, whoever uses it.
Do CALs for an earlier Windows Server version work on a later one?
No. A pack works with its own Windows Server version or an earlier one. A Windows Server 2022 pack, for example, works with 2022, 2019 and 2016 session hosts, but not with 2025.
How many packs do I need for 80 people?
Two packs of 50 User CALs cover 100 people. With Device CALs, count the devices that connect instead. Check Microsoft’s licensing terms for your setup.
