Windows is the correct product name.
Windows 10/11 Business is a subscription that enhances Windows Pro devices for small and medium businesses with enterprise‑grade security and simplified management. It adds Windows Defender security controls, Windows Autopilot for modern deployment, and enhanced manageability through mobile device management (MDM).
Requirements: Devices must run Windows 10/11 Pro with the Fall Creators Update or later, be joined to Microsoft Entra ID (formerly Azure AD), and be managed by an MDM solution to use these capabilities.
Ideal for organizations standardizing secure, cloud‑based PC management with streamlined provisioning and policy control. For broader productivity and security benefits, pair with Microsoft 365 Business Premium.
