Windows Central / Microsoft·medium signal

Microsoft's May 12 security update for Windows 11 introduces AI agent monitoring in the Taskbar, surfacing real-time status updates from background agents via hover previews. The first integration is Microsoft 365 Copilot's Researcher agent showing live progress on report generation. Developers can integrate their own agents via the new Windows.UI.Shell.Tasks API — optional for users, not enabled by default.
