Description

What is included in Windows Server 2019 Device CAL?

Device access – Licenses one device to reach server services
Shared use – Any number of users on that device
Core services – File, print, DNS, Active Directory sign-in
Backward coverage – Valid for Server 2019 and earlier versions
Mixing allowed – Combine with User CALs in one environment
Core Capacity – One device, unlimited users; no RDS rights included
Important – This is not an RDS CAL; Remote Desktop sessions require separate RDS CALs.

What are the main benefits of Windows Server 2019 Device CAL?

A Windows Server 2019 Device CAL is the access license that legally permits one device to use a Windows Server 2019 machine. It is counted per device rather than per person, so several staff sharing the same workstation are all covered by a single CAL.

Lower cost – Cheaper when devices outnumber your staff
Shift friendly – One CAL covers all device users
Simple counting – Tally hardware, not individual accounts
Audit cover – Keeps Server 2019 access compliant
Flexible mix – Pair with User CALs as needed
No expiry – The CAL right does not lapse

What does a Windows Server 2019 Device CAL do?

A Device CAL grants one device the legal right to access services on a Windows Server 2019 server, no matter how many people use that device. The CAL is required separately from the server licence itself: the per-core server licence covers installing the operating system, while CALs cover the clients that connect to it. In practice this means a single till, kiosk, or shared shop-floor PC needs just one Device CAL even if ten employees log in on it during the day. The licence applies to standard network services such as file shares, print queues, DNS, and Active Directory authentication. It does not enable Remote Desktop sessions, which are licensed under a separate RDS CAL.

Compares the 2019, 2022, and 2025 releases to help determine whether upgrading to the latest version is worthwhile.

Who is a Device CAL best suited for?

A Device CAL is the cheaper choice when an organisation has fewer devices than users, typically because staff share machines. The classic case is shift work: a warehouse, factory, hospital ward, or retail floor where three people use the same terminal across a 24-hour rota only needs one CAL for that terminal instead of three User CALs. This directly lowers the licence count where headcount is high but hardware is fixed. By contrast, if your staff each carry a laptop and a phone that both hit the server, User CALs usually work out cheaper, because one User CAL covers all the devices a single person uses.

What is the difference between a Device CAL and a User CAL?

A Device CAL licenses one physical device for unlimited users, while a User CAL licenses one named person for unlimited devices. The deciding factor is whether you have more devices or more people. A Device CAL fits shared hardware used by rotating staff; a User CAL fits a worker who connects from a desktop, a laptop, and a phone. You cannot cover the same access with both types at once, but you are allowed to mix Device and User CALs within the same Server 2019 environment to match each part of the workforce.

Does a Windows Server 2019 Device CAL include Remote Desktop (RDS) rights?

No. A standard Windows Server 2019 Device CAL covers normal network services only and does not grant Remote Desktop Services access. To let a device run a full Remote Desktop session on the server, you need a separate RDS Device CAL on top of the standard CAL, plus an RD Licensing role to issue it. This is a frequent and costly buying mistake: ordering only standard CALs and then finding remote sessions stop once the built-in grace period ends. If your goal is multiple simultaneous remote desktops, budget for both the Windows Server CAL and the matching RDS CAL.

Is a 2019 CAL compatible with newer Windows Server versions?

A Windows Server 2019 CAL is backward-compatible only: it covers access to Server 2019 and earlier server versions, but not Server 2022 or 2025. If you upgrade the server operating system to a newer version, your existing 2019 CALs do not carry forward and you must buy CALs that match or exceed the new server version. Before purchasing, confirm which Windows Server version your server actually runs, so the CAL version lines up. Buying 2019 CALs for a 2022 server is the most common reason a purchase ends up non-compliant.

What should you check before choosing a Device CAL?

Check three things: your device-to-user ratio, the exact server version, and whether remote desktop is involved. Count the devices that actually touch the server versus the number of people, and pick Device CALs only if devices are fewer. Confirm the server is running Windows Server 2019, since the CAL must match or be newer than the server it accesses. Finally, decide whether anyone needs Remote Desktop sessions, because that requires additional RDS CALs the standard Device CAL does not cover. A standard CAL ships as a proof-of-licence document rather than installable software, so there is no separate client program to deploy.

Frequently asked questions about Windows Server 2019 Device CAL

Do I still need a server licence if I buy CALs?

Yes. CALs only license the clients that connect; they do not license the server itself. You still need a separate Windows Server 2019 licence for the machine, and the CALs sit on top of that to cover the devices accessing it.

How many Device CALs do I need?

You need one Device CAL for each device that accesses the server, regardless of how many people use that device. Count the physical machines that connect, not the number of employees.

Can I switch between Device and User CALs later?

CALs are assigned by type and are not interchangeable once allocated, but you can mix both kinds across one environment. Many organisations assign Device CALs to shared terminals and User CALs to mobile staff at the same time.

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.
