This product provides 100 user Client Access Licenses (CALs) for Windows Server 2025, enabling up to 100 users to legally access your Windows Server environment. As a core component of Microsoft's licensing model, each user or device that connects to a Windows Server requires a CAL. This 100-user CAL bundle is designed for businesses expanding their server infrastructure, ensuring compliance while simplifying license management.

Who it's for

This CAL license is designed for IT administrators and procurement managers in small to medium-sized businesses that need to scale user access to a Windows Server 2025 environment. It suits organizations with up to 100 employees who require server access for file sharing, application hosting, or remote desktop services. It is also appropriate for managed service providers (MSPs) deploying Windows Server for multiple clients, as the user CAL model allows flexible assignment. For larger enterprises, multiple 100-user CAL bundles can be combined to cover the entire workforce.

FAQ

Can I use these CALs for Windows Server 2025 Standard edition? Yes, Windows Server 2025 CALs are edition-agnostic: they work with both Standard and Datacenter editions. However, you must ensure the server itself is properly licensed with the corresponding Windows Server 2025 license. CALs are required per user or device accessing the server, regardless of the edition.

How are the CALs delivered and activated? After purchase, Lizensa sends you a digital delivery email containing the license key and a step-by-step activation guide. The key is typically a multi-use volume license key that you install on your server or manage through Microsoft Volume Licensing Service Center (VLSC). Activation is straightforward, and Lizensa support is available if you encounter any issues.
