Ripple effect: Microsoft may be backing away from the Copilot+ PC branding, but it's doubling down on the bigger idea behind it: turning AI into a layer that actively runs your computer and gets work done for you. Its latest Copilot overhaul pushes that vision further than before, combining Office, coding tools, and autonomous agents into what CEO Satya Nadella calls a "new OS for work." Public testing begins in the coming weeks.

Microsoft recently unveiled a major overhaul for Copilot's business tools. The new suite hands the AI assistant more control in Office, embeds GitHub Copilot's functionality into professional toolchains, and automatically coordinates tasks between team members.
The new Copilot implementation, which Microsoft CEO Satya Nadella calls a "new OS," consists of several parts. One of them, simply called Home, lets users chat with Copilot as it examines files to offer recommendations on how it can help. Home can also take over Office 365 apps such as Word, Excel, and PowerPoint to automatically draft files for users to edit.

Another tool, Code, builds apps based on natural-language prompts using the same tools as GitHub Copilot. Microsoft claims that Code uses Microsoft IQ to maintain contextual knowledge of users' work environments beyond what it currently sees onscreen.
Lastly, Autopilot, a rebrand of Scout, offers the highest level of automation. After users provide it with a role and an objective, Autopilot handles various tasks such as scheduling meetings, following up with contacts, watching channels, starting and resuming projects, and more, all without further human input. The cloud-hosted feature also works 24/7, working across Teams, Outlook, documents, and other programs while remaining in constant contact with teammates.

Home and Code will enter Microsoft's Frontier program in the coming weeks, while Autopilot will be available in private preview at the end of this month. Another aspect of Home, called Today, will enter private preview in October. Today aims to show users a unified information space with details from emails, Teams chats, meetings, and other sources while also drafting documents and proposing schedules.
Nadella's "Copilot OS" claim sounds a lot like the supposedly defunct Project Aion, which would have become a separate OS built around Copilot running within an Edge shell. Users would operate apps and create documents by chatting with Copilot instead of controlling them directly. Although Microsoft might have shelved Aion, a video demonstration of the new Copilot update closely resembles certain aspects of it.

Notably, this latest push to embed Copilot in users' systems follows an admission from Microsoft and Qualcomm that the Copilot+ PC brand has been abandoned, with the companies acknowledging that consumers simply don't care about "AI PCs." It remains unclear whether Home, Code, and Autopilot will be next in a growing trail of shelved AI initiatives such as Copilot+ PCs and Recall.
Microsoft wants Copilot to become an "OS" that writes your documents and manages your work
