About this licence

The Windows Server 2025 CAL (Client Access License) is required for users or devices to legally connect to a server running Windows Server 2025. This license enables access to server services and functions but does not include the server software itself. Each CAL must be assigned to either a user or a device, depending on your licensing model. Windows Server 2025 CALs support access to both Standard and Datacenter editions of Windows Server 2025. They allow connection to file servers, print servers, and other network services hosted on Windows Server 2025. The CALs are essential for businesses to remain compliant with Microsoft's licensing requirements. The key can be activated through Microsoft's Volume Licensing Service Center or other authorized activation methods. Each CAL is valid for the version specified and does not automatically renew unless additional licenses are purchased. Every purchase includes a valid VAT invoice and activation support if needed. The license is intended for lawful resale and use in compliance with Microsoft's licensing terms. The CAL does not include server software or any additional services beyond client access rights.
