Microsoft just entered the autonomous agent race in a meaningful way. Copilot Tasks — announced today and rolling out in preview — is not an enhancement to the existing Copilot assistant. It’s a fundamentally different product: a background agent that runs on a dedicated cloud PC, with its own browser, that accepts natural language instructions and executes them while you’re doing something else entirely.
This puts Microsoft in direct competition with OpenAI’s Operator and Anthropic’s computer-use products. And given Microsoft’s distribution advantages, it’s a competitive move worth taking seriously.
What Copilot Tasks Actually Is
The product is best understood by what it does differently from regular Copilot:
- It runs in the background. You give it a task, it runs on a remote cloud PC, and you come back to results. You don’t watch it work in real time (though you can check in).
- It has its own browser. The agent navigates the web, fills forms, logs in to services (with your credentials, stored in the vault), and interacts with web UIs — not just APIs.
- It accepts scheduled and recurring tasks. “Every Monday morning, pull last week’s top support tickets and put them in a spreadsheet” is the kind of thing this is built for.
- It checks in for sensitive actions. Before it sends a message, makes a purchase, or takes any action that moves money or data, it pauses and asks for confirmation. Microsoft calls this the “approval gate.”
The natural language interface is deliberately simple. You type what you want in plain English. The agent breaks it into steps, executes them, and reports back with what it did — including a log of every action it took.
The Cloud PC Architecture
The technical infrastructure here is interesting. Microsoft is running the agent on Windows 365 Cloud PC infrastructure — the same product it sells to enterprises for remote work. Each agent session gets an isolated virtual machine, its own browser profile, and a credential vault that is never exposed to the agent model itself. The agent can use the credentials (it can trigger a login), but it can’t read them.
This isolation model is a direct response to the prompt injection and credential theft attacks that have plagued earlier computer-use agent demos. By keeping credentials in a separate vault that the LLM can’t directly access, Microsoft is trying to close the most obvious attack surface.
How It Compares to OpenAI Operator
OpenAI’s Operator, which launched in January, pioneered the “agent with a browser” category for consumer use. Copilot Tasks is clearly inspired by it — but there are some notable differences:
| Feature | Copilot Tasks | OpenAI Operator |
|---|---|---|
| Background execution | ✅ Yes | ✅ Yes |
| Scheduled/recurring tasks | ✅ Yes | ❌ No (one-shot) |
| Approval gate for sensitive actions | ✅ Yes | ✅ Yes |
| Cloud PC isolation | ✅ Full VM | Sandboxed browser |
| Integration with Microsoft 365 | ✅ Native | ❌ No |
The scheduled and recurring task support is the most significant differentiator. Operator is fundamentally a one-shot tool — you give it a task, it runs, it’s done. Copilot Tasks can be set up to run on a schedule, which opens a much wider range of automation use cases.
The Microsoft 365 integration is also significant. Copilot Tasks has direct access to your calendar, email, OneDrive, and Teams data — things Operator can only reach by navigating to Outlook.com or SharePoint in a browser.
What This Means for the Agentic AI Landscape
Today’s launch, combined with Apple’s Xcode 26.3 release and GitHub Copilot’s agent updates, represents something worth naming: February 26, 2026 is a landmark day for agentic AI in production. Three of the largest technology platforms — Apple, Microsoft, and GitHub — all shipped meaningful agent capabilities on the same day.
For practitioners, Copilot Tasks is worth evaluating if you’re already in the Microsoft 365 ecosystem. The scheduled task support and M365 integration are genuine advantages over the current alternatives. The approval gate architecture is also a thoughtful safety design that other products should probably copy.
The preview is rolling out now to Copilot Business and Enterprise users. Microsoft hasn’t announced a general availability date.
