Microsoft Launches OS-Level Sandbox for AI Agents

Microsoft unveiled Microsoft Execution Containers (MXC) at its Build developer conference, an OS-level sandbox that enforces strict boundaries on what AI agents can access. Built into Windows itself, the policy-driven layer lets developers and IT administrators define agent permissions enforced at runtime by the OS kernel. The move addresses a critical security gap in the AI industry: what happens when an autonomous agent malfunctions or acts outside intended parameters. OpenAI and Nvidia are already on board, signaling broad industry support for the platform.
