Microsoft Core CAL – User Access Licence, Unlimited Versions (SKU W06-00655)

The Microsoft Core CAL – User Access Licence provides a perpetual, single‑user entitlement to all current and future Windows Server editions. Designed for organisations that need flexible, future‑proof server access, this licence is assigned to an individual employee rather than a device, ensuring that the right person can work from any workstation, laptop or virtual environment. With no version limits, the CAL automatically covers new Windows Server releases as they become available, eliminating the need for additional purchases or upgrades. This simplifies licence management, reduces administrative overhead and protects your IT budget from unexpected costs. Ideal for businesses, educational institutions and charities that require reliable, compliant server access for their staff. The licence is delivered as an online volume (OLV) product, enabling rapid provisioning through Microsoft’s Volume Licensing portal. Once assigned, the user can instantly connect to any Windows Server role – from file and print services to advanced cloud‑integrated workloads – without further licensing complications.
