Microsoft Launches New Copilot Studio Preview
Microsoft has released a redesigned Copilot Studio in preview, migrating the backend engine and replacing legacy 'topics' with an LLM-driven model centered on 'Skills'. The new builder emphasizes six areas including Microsoft IQ (Work IQ, Fabric IQ, Foundry IQ), Skills, Tools (connectors), Knowledge, Connected Agents, and Memory. The preview improves UI/UX, a richer preview/test experience showing agent reasoning, and introduces Workflows replacing Agent Flows. Current limitations in preview include restricted knowledge source types (external sites, SharePoint, OneDrive) and limited solution/export access.
Microsoft (a major enterprise platform) moved Copilot Studio onto a new LLM-first engine, added enterprise data grounding (Microsoft IQ) and Skills—changes that materially affect how organizations build and deploy conversational agents.

Microsoft previews Copilot Tasks for cross-app actions
Microsoft has opened a limited research preview of Copilot Tasks, a capability that interprets natural-language requests, plans multi-step workflows, and executes tasks across applications using its own computer and browser while requiring user approval for consequential actions. The preview began February 26, 2026 for a restricted group with a waitlist; Microsoft has not disclosed pricing, a full public release schedule, or enterprise administration/compliance details. Microsoft positions Copilot Tasks as an evolution from providing answers to actually completing workflows (recurring monitoring, document generation, logistics/shopping). The announcement emphasizes staged rollout and user consent, and the preview raises governance, access-control, auditability, and cost/licensing questions for organizational deployment.
Visual Studio Adds Custom Copilot Agents and Profiler
Visual Studio 2026's March update (v18.4.0, released March 10) introduces declarative custom agents (defined via .agent.md files) that let teams encode workflows and toolchains into Copilot agent mode. The update also enhances the profiler by integrating it with unit tests so runtime metrics (elapsed time, CPU, memory) surface inline during debugging and Copilot can suggest optimizations or scaffold benchmarks. Microsoft published an MSVC Build Tools 14.51 Preview showing measurable runtime improvements (notably +6.5% integer Arm64 with PGO). Additional changes include a find_symbol tool for agent-mode symbol navigation, JSON editing in the core editor, HTML rich copy, Smart Watch suggestions in debug watches, and enterprise MCP governance via GitHub allowlists. The release emphasizes making AI assistance a platform-level capability integrated into the development lifecycle rather than a basic autocomplete feature.
Copilot Cowork: AI Handles Microsoft 365 Tasks
Microsoft is expanding its 365 Copilot with Copilot Cowork, an AI feature that can automatically generate and execute work plans across Outlook, Teams, and Excel. It analyzes data from emails, files, meetings, and documents, creating milestones, tracking progress, and requesting decisions as needed. Copilot Cowork aims to move beyond chat-style support to autonomous task execution, using a system called Work IQ to orchestrate workflows across apps. The solution can prepare briefs, presentations, and analyses for meetings and product launches, and can perform enterprise research and financial analyses. It is currently being tested with select customers, with wider availability planned for the end of March 2026 via the Frontier program. The article also notes Microsoft’s broader use of multi-model AI, including Claude from Anthropic, within Copilot Studio and related tools, all operating under Microsoft 365 security and governance controls.
