Microsoft announced two distinct changes to Copilot in 2026: a May redesign of the Microsoft 365 Copilot app and its presence in Office apps, followed by September’s Home, Code, and Autopilot capabilities. The May update focused on how people navigate and work with Copilot; the later announcement outlined a broader work experience that brings chat, Office work, solution-building, and tasks that can continue independently into one product direction. Microsoft described a staged rollout, not immediate access for every user.
What changed in Microsoft Copilot?
The announcements came in two stages. On May 28, Microsoft described a redesign of the Microsoft 365 Copilot app and a more consistent way to use Copilot inside Microsoft 365 apps. On September 25, it announced Home, Code, and Autopilot—new capabilities that extend beyond the interface changes.

| Announcement | Main focus | What Microsoft said about access |
|---|---|---|
| May 28, 2026 | App navigation, prompt workspace, session recall, and Copilot entry points in Word, Excel, and PowerPoint | Microsoft described the redesigned experience and reported results; the announcement does not establish current access for every user. |
| September 25, 2026 | Home, Code, Autopilot, and tighter integration with Word, Excel, and PowerPoint | Home and Code were to roll out gradually through Frontier; Autopilot was to expand to Private Preview. |
What changed in the May Microsoft 365 Copilot redesign?
A more flexible prompt workspace
Microsoft described a larger, task-aware prompt area with contextual tools and controls. It can expand for longer work and preserve structure and inline formatting. The design uses progressive disclosure: the initial interface stays focused, with more controls appearing when they are useful.
Navigation and session continuity
The app’s expandable navigation brings agents, conversations, and history into view. Microsoft also described pinning and session recall, intended to make it easier to return to work rather than start over each time.
Copilot in Office apps
In Word, Excel, and PowerPoint, Microsoft said Copilot would have a consistent entry point. People could use it in a side pane to get suggestions or request changes, or invoke it directly on a paragraph, cell, or slide. The May post named Designer, Researcher, Word, Excel, and PowerPoint among the capability-focused agents.
Work context and controls
Microsoft said Work IQ can draw on work context such as emails, files, chats, and meetings, and that users can control when it is active. That is Microsoft’s description of the feature; the announcement does not independently establish how it performs across different organizations or configurations. Read Microsoft’s May 28 announcement.
What are Home, Code, and Autopilot?
Microsoft’s September announcement presented three capabilities as the center of its newer Copilot direction. Jared Spataro, Microsoft’s Chief Marketing Officer, AI at Work, wrote, “We’re reimagining Microsoft Copilot to enable work as it evolves.”
Home: a starting point for work
Home brings Chat and Cowork together as a place to begin and manage work. Microsoft also previewed Today in Home, but the announcement does not establish its general availability.
Rank #3
Code: build solutions with natural language
Code is intended to help users build solutions—including applications and automations—using natural language. Microsoft described the capability, but the announcement does not provide a full technical specification, supported-language list, or comparison with dedicated development tools.
Autopilot: tasks that continue while you are away
Microsoft described Autopilot as an agent that can keep working on tasks while a user is away. The announcement does not establish that it can complete every task without user review, nor does it specify universal access or the full range of supported workflows. Microsoft also previewed @Copilot in Teams.
Office integration across the newer experience
Microsoft said Word, Excel, and PowerPoint would be built into the Copilot experience, with content synchronized between Copilot and the Office applications. This is broader than the May design change: the May announcement emphasized a side pane or direct invocation in a document, while September described Office apps as integrated into Copilot. Read Microsoft’s September 25 announcement.
What do Microsoft’s performance and usage numbers show?
Microsoft reported performance and usage figures in its May post. They are vendor-reported results, not independent verification, and the usage comparison should not be read as proof that the redesign alone caused the change.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Load time: Microsoft said the redesigned app loaded more than twice as fast, with load times reduced by over 50%. It based this comparison on customer testing conducted March 10–17, 2026, with approximately 11.06 million users in the treatment group and 11.16 million in the control group. Microsoft defined User Perceived Load Time using the maximum latency of key app-load components.
- Complex chat response time: Microsoft reported a 10% improvement for complex chat prompts; the announcement excerpt does not provide separate independent validation.
- App usage: Microsoft reported increases of 27% in Word, 33% in Excel, 43% in PowerPoint, and 30% in Outlook. These figures compare activity during May 8–12, 2026, after rollout, with May 1–5, 2026, before rollout. They are a before-and-after comparison, not a controlled causal finding in the information Microsoft provided.
When can users access the new Copilot features?
Microsoft said Home and Code would roll out gradually to its Frontier program over the weeks following the September announcement, while Autopilot would expand to Private Preview at the end of September. Its EMEA release likewise described a staged rollout. Those launch statements do not confirm present-day availability for every account, plan, or country. Check Microsoft’s current product information or your organization’s administrator for eligibility and access. See Microsoft’s EMEA announcement.
