Microsoft Events delivers an in-depth exploration of how Windows is enabling large-scale development of secure AI agents, highlighting MCP, agent connectors, and platform-level security upgrades.

Unleash the Future of AI and Agents on Windows Backed by Security

Session Overview

This session from Microsoft Ignite 2025 focuses on expanding Windows as a robust canvas for AI and agent-driven computing. Topics include the Model Context Protocol (MCP), Computer Using Agents (CUAs), technical deployment architectures, and new security models to support billions of specialized agents by 2028.

Key Technical Topics

• Agent Connectors and Registry: Learn how agent connectors allow extensibility and secure interactions between agents, utilizing on-device registries and isolated workspaces for controlled execution.
• Growth Projection: Anticipates the existence of 1.3 billion active agents by 2028 and discusses specialized agent hierarchies for different use cases.
• Platform Security Enhancements: Reviews upcoming security guardrails, risk mitigations, and the need for agent packaging requirements reminiscent of early web security standards.
• MCP Host Architecture: Explains the host, client, and server interaction model enabling agent communication across the platform.
• Technical Demo: The ‘Manus’ demo illustrates agent deployment, isolated execution, and secure handling of agent operations on Windows.
• Addressing Installation and Privacy: Includes strategies to reduce installation friction and enhance user privacy in agent-enabled computing.
• Microsoft Defender Integration: Details plans for integrating device-level security and monitoring for agents via Microsoft Defender, with a focus on audience Q&A around device access concerns.
