What are the main benefits of Windows Server 2019 RDS User CAL?

The RDS User CAL is the access license each user needs to connect to a Remote Desktop Session Host running on Windows Server 2019. It sits on top of the base server license and the standard Windows Server CAL, and it keeps multi-user remote sessions compliant once the grace period ends.

Device Freedom – User connects from laptop, desktop, or thin client.
Compliance Coverage – Keeps RDP sessions legal past the 120-day grace.
No Revocation Loss – Per user CALs are never revoked or reclaimed.
Cross-Domain Issuing – License server issues CALs across domains and forests.
Roaming Workforce – One CAL fits staff who switch machines often.
Type Conversion – Can be converted to Device CALs if needs change.

What does the Windows Server 2019 RDS User CAL actually do?

It grants one user the right to start a Remote Desktop session on a Windows Server 2019 Session Host. Without an RDS CAL, Windows Server only allows two simultaneous administrative RDP connections for maintenance, and any further remote sessions stop working once the 120-day grace period ends. The CAL is requested from a Remote Desktop Licensing server each time the user signs in and is then tied to that user in Active Directory. This is what turns a single server into a working multi-user remote application or desktop environment.

What is the difference between an RDS User CAL and an RDS Device CAL?

A User CAL is assigned to a person and lets that person connect from any number of devices, while a Device CAL is assigned to a machine and lets any number of people use that one device. The per user model suits cases where each employee has their own equipment or works from several devices, such as an office PC plus a home laptop. The per device model fits shift work where multiple staff share the same physical workstations. One practical difference: up to 20% of per device CALs can be revoked through the licensing manager, but per user CALs cannot be revoked at all, so size the user count carefully before buying.

Do I need a separate Windows Server license and Windows Server CAL as well?

Yes. The RDS User CAL is an additional license and does not replace either the base Windows Server 2019 license or the standard Windows Server CAL. The Windows Server CAL covers basic access to server services such as file, print, and DNS, while the RDS CAL specifically covers the Remote Desktop session itself. In practice a remote user needs both: a Windows Server CAL to reach the server and an RDS CAL to run the desktop or app remotely. Buying RDS CALs alone, expecting them to enable a server on their own, is the most common purchasing mistake with this product.

Can a 2019 RDS User CAL be used with newer Windows Server versions?

No. A Windows Server 2019 RDS CAL can only license session hosts running Windows Server 2019 or Windows Server 2016, not 2022 or 2025. RDS CAL compatibility runs backward only: newer CALs cover older hosts, but older CALs never cover newer hosts. So if you plan to move your Session Host to Server 2022 within the license lifetime, a 2019 CAL will not follow it and you would need to buy 2022 CALs. Confirm the exact Windows Server version of your RD Session Host before ordering, because the CAL version must match or exceed it.

What should users check before choosing this CAL?

Confirm three things: the Windows Server version of your Session Host, whether your environment fits the per user model, and that you have a Remote Desktop Licensing server to install the CALs on. The license server must run Windows Server 2019 or later to host 2019 RDS CALs. Per user CALs also cannot be validated in a pure workgroup, so they assume an Active Directory domain for proper assignment. If your users share fixed workstations on shifts rather than carrying their own devices, a Device CAL is usually the more economical choice.

Frequently asked questions about Windows Server 2019 RDS User CAL

Can per user RDS CALs be tracked in a workgroup without Active Directory?

No. Per user RDS CALs are assigned to user accounts in Active Directory and cannot be validated in a workgroup, which is why workgroup sessions get dropped. If you run without a domain, the per device CAL is the type that still works, since it is tied to hardware rather than to a directory account.

Can I convert per user RDS CALs to per device CALs later?

Yes. Installed RDS CALs can be converted between per user and per device using the Convert Licenses option in the RD Licensing Manager console or the Convert-License PowerShell cmdlet. After converting, the Session Host licensing mode must be set to match the new CAL type, or the converted CALs will not be issued.

Do external users such as contractors or clients also need an RDS CAL?

Yes. Every user who connects to the Remote Desktop environment needs an RDS CAL, with no exemption for external contractors, partners, or clients. For a large number of outside users, Microsoft offers an External Connector license as an alternative to buying individual CALs for each one.

What happens when the Remote Desktop licensing grace period ends?

Windows Server 2019 gives a 120-day grace period during which the Session Host role works without a license server. Once it ends, clients without a valid RDS CAL can no longer sign in and see an error stating that no Remote Desktop License Servers are available. Installing your RDS User CALs on an activated license server before that point prevents the lockout.

Legal Information

Legal Information About Our Products

keys.express and keys.discount are online platforms for product keys. The product keys available in our shops for Windows and other software are inexpensive, secure, legal and come with an activation guarantee.

Below you will find the most important legal information about our products.

Unused and Non-Activated Product Keys

We offer exclusively unused and non-activated product keys. The keys have never been redeemed for activation and are fully available to the purchaser for the first-time activation of the respective product. A key that has already been redeemed could no longer be used for a new activation and is therefore not offered by us.

Trading in these product keys is permissible in the European Union and in Switzerland under current case law, provided that the necessary conditions are met. These conditions are as follows:

The software must originally have been placed on the market with the consent of the rightholder within the territory of the EU, another contracting state of the EEA, or Switzerland by way of sale.
The license for the software must have been granted in return for the payment of a fee intended to enable the rightholder to obtain remuneration corresponding to the economic value of the copy of the software.
The rightholder must have granted the first acquirer the right to use the software permanently (for an unlimited period).
Any improvements and updates that the subsequently downloaded computer program has compared to the originally downloaded one must be covered by a maintenance agreement concluded between the rightholder and the first acquirer.
The original licensee must have made their own copies unusable.

This trade is legally permissible because the underlying license was already placed on the market with the consent of the rightholder within the EU/EEA or Switzerland in return for appropriate remuneration. As a result, the so-called principle of exhaustion has taken effect, which permits the resale of individual product keys — in particular those originating from volume license agreements. Microsoft or the respective software provider has already received appropriate remuneration for this.

keys.express and keys.discount ensure that the aforementioned conditions are met and that the lawful use of the software is guaranteed. The requirements arising from European legislation are also observed in Switzerland.

Important note: The acquisition of a product key through the transmission of a combination of numbers and letters in digital form does not, in itself, constitute a license for the lawful use of the program. The license only arises from the respective installation and the associated acceptance of the manufacturer's terms of use.

Legal assessment by Swiss lawyers

Overview of the Most Important Legal Information

We offer unused, non-activated product keys for the activation of the respective computer programs. The key alone is not yet a license.
The license only arises from the respective installation and the resulting acceptance of the terms of use. These terms of use govern the right to use the software between you and the respective manufacturer.
The principle of exhaustion has, as a rule, taken effect — i.e. the license is "used up" — as soon as it was lawfully placed on the market for the first time. The products concerned are software placed on the market for unlimited-time use in the form of an activatable product key with the option to download the program. Microsoft or the respective software provider has received appropriate remuneration for this.
You gain access to particularly attractively priced product keys from volume license agreements, which are to be treated legally in the same way as parts of volume licenses upon first acquisition.
The software itself is always the same original software that is also obtained through official download channels or manufacturer sources. You are therefore not paying for a different or inferior version, but for a valid activation key or a corresponding license.
