Microsoft Core CAL – Device Access Licence, Unlimited Versions (SKU W06-00660)

The Microsoft Core CAL – Device Access Licence provides a perpetual, single‑device client access right for Windows Server. Designed for organisations that allocate a dedicated workstation, kiosk or thin client, this CAL grants unlimited version rights, meaning the licensed device can connect to any current or future Windows Server release without additional purchases. It is a no‑level, add‑on product that can be combined with existing CAL packs to scale your licensing portfolio efficiently. With a one‑time purchase and no recurring renewal fees, the licence delivers long‑term cost certainty while simplifying compliance. IT managers can confidently deploy the device across multiple sites, knowing the licence remains valid regardless of server upgrades. This flexibility makes it an ideal solution for shared workstations, point‑of‑sale terminals, and other fixed‑hardware environments that require reliable, future‑proof server access.
