Windows 11 Preview Adds Agentic AI Toggle as Microsoft Issues Security Warning

Overview

• A new “experimental agentic features” switch is rolling out to Windows 11 Insiders in the Dev and Beta channels, enabling apps to use agentic capabilities.
• Microsoft’s support document outlines Agent Workspace, where agents run in separate Windows sessions with their own accounts and lightweight isolation that scales CPU and memory use.
• The company warns users to enable the feature only if they understand the security implications, keeping it off by default and noting agents get read and write access to Documents, Downloads, Desktop, Videos, Pictures and Music when enabled.
• Preview reporting shows agents can operate in the background and interact with apps and files to automate multi‑step tasks, with logging and supervision intended to track activity.
• Microsoft lists security pillars such as non‑repudiation, confidentiality and authorization, says Copilot Actions will be an early adopter, and plans to allow third‑party agents under the same requirements.
