Windows adds containment controls for local AI agents
Microsoft announced Microsoft Execution Containers on June 2, 2026 as an early-preview SDK for policy-driven agent isolation on Windows and Windows Subsystem for Linux. The post says Agent 365 policy controls with Microsoft Entra and Intune can apply constraints to agents, including process isolation and session isolation scenarios.
SharePoint and Teams admins are already being pulled into Copilot readiness, permissions cleanup and agent governance. Local agents add another surface because they can read files, invoke services, modify environments and chain actions faster than a normal user would. The useful part of this announcement is the containment direction. Instead of treating every agent as a fully trusted user session, Microsoft is building controls for what an agent can access, which session it runs in, and how its activity can be attributed and managed.
Analysis
Inventory the local agent tools already appearing on managed devices, then define the file, network, identity and session boundaries you would expect before allowing a pilot. Treat MXC and Agent 365 as governance inputs, not as a reason to skip permissions cleanup.
