Microsoft is giving Copilot the power to stop suggesting edits and start making them.

The company this week pushed its "agentic" Copilot features into general availability across Word, Excel, and PowerPoint, turning the assistant from a sidebar prompt into something that edits documents, tweaks spreadsheets, and builds slides in place

"Copilot can now take actions on your behalf across Word, Excel, and PowerPoint," Redmond said, pitching the update as a move toward software that doesn't just respond, but gets on with the job. The feature is on by default, but must be activated by users through a very prominent prompt on the right side. As always, you can turn off Copilot completely by following the instructions on this page.

In practice, it's the next step in a strategy that has already seen the AI assistant threaded through Windows, GitHub, and just about every product Microsoft can get its hands on.

That approach hasn't exactly been universally loved. Critics – including folks over at Mozilla – have taken aim at what looks a lot like forced integration, arguing that Microsoft is less about "adding features" and more about quietly making Copilot unavoidable.

• Microsoft's GitHub grounds Copilot account sign-ups amid capacity crunch
• Microsoft: Removing some Copilots will improve Windows 11
• Notepad sheds Copilot from toolbar as Microsoft gives subtlety a try
• Gartner suggests Friday afternoon Copilot ban because tired users may be too lazy to check its mistakes

The shift to agentic behavior only adds fuel to that argument. Suggesting a better sentence is one thing, but taking a more active role in rewriting documents or restructuring spreadsheets is another, even if Microsoft frames it as working alongside the user rather than acting independently. 

Trust is already a sore spot, as recent scrutiny of Copilot's terms has highlighted that the AI may be unreliable and shouldn't be depended upon on for important decisions, even as it is being pushed deeper into everyday workflows. At the same time, admins have found themselves dealing with features turning up unannounced, as automatic deployments pushed Copilot further into enterprise environments, whether they were ready or not.

Microsoft says that it has learned from that pushback. The company is emphasizing visibility and control, with users able to review changes and keep a handle on what Copilot is doing. It can also show what it's working on during multi-step edits, rather than leaving users guessing.

Redmond added that the "new default experience is already proving more useful in real work…" based on early customer feedback, though whether that feedback reflects the average Register reader is another question.

For Microsoft, the move makes sense. If Copilot is going to justify its place – and its price tag – it needs to do more than sit in a sidebar. ®
