Microsoft Windows Server 2012 DEVICE CAL - Product Key

Windows Server 2012 Device CAL system requirements

Download Windows Server 2012 Device CAL: the licence is sent by email

Windows Server 2012 Device CAL is not a software package to be run on the client device: it is a licence document that grants a physical or virtual device the right to access Windows Server 2012 and 2012 R2 services, regardless of which user is currently using it. After purchase from Mr Key Shop, the product key and documentation are sent directly via email. There is no client-side installer to download: the CAL is registered on the server, either via the Remote Desktop Services Licence Manager for RDS Device CALs, or via the compliance logs for standard access CALs to Windows Server services.

Installing Windows Server 2012 Device CAL: management is entirely on the server

Nothing needs to be installed or configured on the client device. RDS Device CALs are registered via the RDS Licence Manager console on Windows Server 2012, which can be accessed via Remote Administration Tools. Each CAL must be linked to a device that can be consistently identified—either by machine name or MAC address—and the assignment record must be archived in the organisation’s compliance records. For Standard Access CALs for Windows Server services, the process is entirely documentation-based: no agents to deploy, no client-side wizards, just proper record-keeping for any audit checks.

Windows Server 2012 Device CAL activation: licence key and device assignment

The product key received from Mr Key Shop is the official document certifying the purchase and must be retained in the organisation’s compliance records. For RDS Device CALs, the procedure is initiated from the RDS Licence Management console on the server: select the licence programme type, enter the code received and specify the number of CALs purchased. The server updates the count of available licences and distributes them to devices in accordance with the policy configured by the administrator. For standard CALs, activation is complete once the licence certificate has been correctly archived for Microsoft audit purposes.

Frequently Asked Questions about Microsoft Windows Server 2012 Device CAL

• What is a Windows Server 2012 Device CAL?
  The Device CAL (Client Access Licence) is the licence that authorises a specific device to access Windows Server 2012 services. Unlike the User CAL, which is tied to the user, the Device CAL is tied to the device: anyone connecting to the server from that machine is covered by the same licence. It is the most efficient solution when several people take turns using the same terminal, such as in work shifts, shared workstations or kiosks, and where the number of devices is fewer than the total number of users.

• What is the difference between a Device CAL and a User CAL for Windows Server 2012?

• Does the Device CAL also cover Windows Server 2012 R2?
  Yes. A Device CAL for Windows Server 2012 is valid for both the base version and 2012 R2. Microsoft CALs are also backwards compatible: they cover access to server versions prior to 2012. The reverse is not true: a CAL for earlier versions does not authorise access to Windows Server 2012.
• Does Windows Server 2012 still receive security updates?
  No. Extended support ended on 10 October 2023. Microsoft no longer releases routine security patches for this version. Customers requiring continuity can access Extended Security Updates (ESUs) via a paid Microsoft channel, but this is a temporary measure. Migration to a supported version is the recommended solution.
• How many Device CALs are required?
  One for each device that accesses the server’s services, regardless of the number of users or active sessions. If five workstations connect to the server, five Device CALs are required, even if several people take turns using each one throughout the day.
• When should you NOT choose Windows Server 2012 Device CALs?
  If each user accesses the server from multiple personal devices, the User CAL provides broader coverage with a single licence per user. If the server is already running Windows Server 2016, 2019 or 2022, the CALs must match the version in use: a 2012 CAL does not authorise access to later versions. Finally, for environments with Remote Desktop Services enabled, always check that the CALs purchased are specifically RDS Device CALs and not Basic Access CALs for Windows Server services.
