Microsoft Windows Server 2019 DEVICE CAL - Product Key

Microsoft Windows Server 2019 Device CAL system requirements

Download Microsoft Windows Server 2019 Device CAL:

Microsoft Windows Server 2019 Device CAL is not software to be installed on the client device: it is an access licence that authorises a specific device to connect to the services of the Windows Server 2019 server, regardless of how many users are using it. After purchasing from Mr Key Shop, you will receive the product key and licence documentation by email. There is no client-side installation file: CAL management takes place entirely on the server, via the administration console and, for RDS Device CALs, via the Remote Desktop Services Licence Manager.

Install Microsoft Windows Server 2019 Device CAL:

The Device CAL does not require any installation on the authorised device. On the Windows Server 2019 server, RDS Device CALs are registered in Remote Desktop Services Licence Manager, which can be accessed via the server’s Remote Administration Tools. For standard access CALs for Windows Server services, compliance is managed through documentation: each Device CAL must be assigned to an identifiable device (typically via machine name or MAC address) and tracked in the organisation’s licence records. Microsoft verifies CAL compliance during audits, not through automatic technical blocks on the client.

Activate Microsoft Windows Server 2019 Device CAL:

The product key received via email from Mr Key Shop serves as proof of purchase and the licence entitlement for the Device CAL. Keep it together with your organisation’s licence compliance documentation. For RDS Device CALs, activation takes place in the server’s RDS Licence Manager via the licence installation wizard: select the licence programme type, enter the code and specify the number of CALs purchased. The server records the available licences and assigns them to authorised devices in accordance with the policy configured by the system administrator.

Frequently Asked Questions about Microsoft Windows Server 2019 Device CAL

• What is a Windows Server 2019 Device CAL?
  A Client Access Licence (CAL) is a licence that authorises access to the services of a Windows Server. The Device CAL authorises a specific device, identified by its machine name, MAC address or other identifier, to connect to the server, regardless of how many users are using it. It is the right choice when several users take turns using the same device or when the number of devices is fewer than the number of users accessing the server.

• What is the difference between a Device CAL and a User CAL for Windows Server 2019?

• Does a Device CAL for Server 2019 also cover earlier versions of the server?
  Yes. Microsoft CALs are backwards compatible: a Device CAL for Windows Server 2019 also authorises access to earlier versions of Windows Server (2016, 2012, etc.). The reverse is not true: a CAL for an earlier version does not cover access to Windows Server 2019.
• Is Windows Server 2019 still supported?
  Yes. Windows Server 2019 is on extended support until 9 January 2029. Microsoft releases regular security updates for this version, which remains an actively supported server platform for on-premises and hybrid environments.
• How many Device CALs do I need for my environment?
  One Device CAL is required for each device that accesses the services of the Windows Server 2019 server, regardless of the number of users using it or the number of sessions open at the same time. The count is based on the number of authorised physical or virtual devices, not on concurrent connections.
• When should you NOT choose a Windows Server 2019 Device CAL?
  If users access the server from multiple different devices – such as a desktop PC, company laptop, tablet or smartphone – the User CAL is more cost-effective as it covers all of that user’s devices with a single licence. If the server environment is Windows Server 2016 or earlier, you will need CALs for the corresponding version: CALs are not interchangeable with higher versions. If you are managing an environment with Remote Desktop Services (RDS), check that the CALs purchased are specifically RDS Device CALs and not just standard Windows Server service access CALs.
