Your AD DS domain has 100 Windows 10 client PCs and no deployment infrastructure. The company bought Windows 11 licenses via volume licensing. To upgrade the PCs while keeping licensing costs minimal, what do you recommend?

Microsoft Deployment Toolkit (MDT) is the most cost-effective solution for upgrading 100 Windows 10 PCs to Windows 11 in an environment without existing deployment infrastructure. MDT is a free tool from Microsoft that allows for automated deployment of operating systems and applications. It integrates with Windows ADK and can perform in-place upgrades or bare-metal deployments. Windows Autopilot is primarily for new device provisioning and requires Microsoft Intune or Configuration Manager, adding complexity and cost. Configuration Manager is a powerful enterprise management solution but requires significant infrastructure investment and licensing, making it unsuitable for minimizing costs in this scenario. Subscription activation is a licensing feature, not a deployment tool, and doesn't address the upgrade process itself.
