FAQ: Microsoft Windows Server 2016 RDS 10 Device CAL

1. What is Microsoft Windows Server 2016 RDS 10 Device CAL?

Microsoft Windows Server 2016 RDS 10 Device CAL is a package of 10 RDS access licenses assigned to devices. It is not a program or system installer, but a license document that authorises the use of Remote Desktop Services in a Windows Server 2016 environment. This license allows a specified number of devices to legally connect to the server in remote desktop mode or use applications published by RDS.

In practice, this means that if a company provides employees with a remote desktop, a warehouse program, ERP, or other applications running on the server, the server license alone is not enough. Additional access licenses, i.e., CAL and RDS CAL, are also required.

2. What does the CAL abbreviation mean and why is it necessary?

CAL is an abbreviation for Client Access License, i.e., a user or device access license. In the Microsoft environment, there are regular access licenses for Windows Server and additional RDS CAL licenses if access is via Remote Desktop Services.

This distinction is important: when purchasing a server, you acquire the right to run the server system, but not automatically the rights for all people and computers to use it. This is why CAL is an element of license compliance. In the case of the Microsoft Windows Server 2016 RDS 10 Device CAL product, we are talking about licenses for 10 specific devices that are to gain access to RDS services.

3. How does Device CAL differ from User CAL?

Simply put: Device CAL is assigned to a device, and User CAL is assigned to a person.

If multiple people use one computer, a Device CAL license is usually more cost-effective because one device uses one license, regardless of the number of changes or operators. This is a common choice in receptions, warehouses, sales points, production halls, and shift offices.

On the other hand, User CAL is better suited when one employee uses multiple devices, such as a desktop computer, laptop, and terminal. In this case, one user license may be more beneficial than several device licenses.

The Microsoft Windows Server 2016 RDS 10 Device CAL variant will be suitable where a company wants to license specific workstations or terminals, not named employees.

4. How many RDS CAL licenses do I need in my company?

You should count how many devices will connect to the server via RDS. If 10 computers, terminals, or thin clients use Remote Desktop Services, a package covering at least 10 Device CALs will be required. If there are more devices, additional licenses need to be purchased.

It is also important that the licenses correspond to the actual use of the environment. It's not just the number of employees in the company that matters, but exactly how many devices access RDS services. In the event of a license audit, it is the compliance of license assignment with actual use that is important.

5. Can one Device CAL licence be used on multiple computers?

As a rule, no. A Device CAL is assigned to one device. If a company has 10 Device licences, then 10 devices are authorised. They should not be treated as a free pool for simultaneous use on any number of computers beyond the purchased limit.

In practice, this means that when expanding infrastructure, replacing terminals, or increasing the number of workstations, it is necessary to verify whether the number of purchased licences still corresponds to the actual state. This is one of the basic elements of maintaining licence compliance.

6. Is this licence legal and how can its authenticity be verified?

The legality of the licence is crucial because RDS CAL is a legal right to use the Microsoft solution, not physical software in a box. Therefore, it should only be purchased from a verified seller who provides full sales documentation and clear delivery terms.

When purchasing from KluczeSoft.pl, the customer receives a legal key or licence details, proof of purchase, and a VAT invoice. It is this complete set of commercial and licence documents that forms the basis for verifying the product's origin. In case of questions before purchase, you can contact us by phone at 00 800 121 1654.

7. Is Microsoft Windows Server 2016 RDS 10 Device CAL downloadable software?

No. This is a very common question. RDS CAL is not a standalone programme that can be installed like office software. It is a licence that is assigned to the Microsoft server environment. Its purpose is to legalise access to remote desktop services within the Windows Server 2016 environment that you already possess.

The customer buys a licence right, not the full server software. The server and RDS role must already exist or be deployed separately. This product complements the environment in terms of compliance and permissions.

8. What does delivery look like and what documents do I receive after purchase?

Licence delivery is usually carried out electronically, which allows for quick transfer of necessary licence information to the customer without waiting for physical shipment. This is a convenient solution for companies that want to quickly supplement missing licences and organise their compliance status.

After purchase, the customer receives:

data necessary for licence implementation,
proof of purchase,
a VAT invoice,
sales support in case of questions regarding the choice of licence variant.

If help is needed in assessing whether the User or Device variant is better, it's worth contacting the sales department at 00 800 121 1654.

9. Can an RDS CAL licence be transferred to another device or to another company?

It depends on the licensing model and assignment terms. In practice, Device CAL is assigned to a device, so it should not be treated as a freely rotating resource. In the event of equipment replacement or organisational changes, caution must be exercised and actions taken in accordance with the licensing rules for the specific product type.

The transfer of licences between entities is a separate issue. For access licences, the most important thing is to maintain full documentation of origin, continuity of the right to use, and compliance with sales terms. If a customer plans to purchase to organise an audit or changes in infrastructure, it's best to confirm the scope of application with an advisor earlier.

10. How to maintain licence compliance with Windows Server 2016 RDS?

The basis is to correctly determine:

whether User CAL or Device CAL licences are required,
how many devices actually use RDS services,
whether the company has the appropriate number of licences to match the actual state,
whether the purchase documents are complete and can be presented.

In the case of Microsoft Windows Server 2016 RDS 10 Device CAL, compliance means that a maximum of 10 assigned devices use the remote desktop services in accordance with the licence's intended use. For companies, this is not only a formal matter, but also a security element during an audit and when organising IT documentation.
