Three Microsoft 365 Updates: LiveStream, New App Icons, and Copilot in File Explorer

Microsoft 365 has been rolling out changes across the board. In this post, I cover three announcements worth paying attention to: a LiveStream event on Copilot features, refreshed app icons across the Microsoft 365 suite, and new Copilot integration directly inside File Explorer.

New Microsoft 365 App Icons

Starting October 1, 2025, Microsoft began rolling out redesigned icons for its core apps — Word, Excel, PowerPoint, Outlook, Teams, and more. The new designs use fluid forms and vibrant colors that reflect the updated Microsoft design language.

If your app icons suddenly look different, this is why. The change is purely cosmetic — no functionality changes — but it signals Microsoft's broader push toward a unified visual identity across Windows, web, and mobile platforms.

Copilot in File Explorer

This is the feature that caught my attention most. Microsoft has started integrating Copilot directly into Windows File Explorer. When you right-click on a document, you can access Copilot features like:

Summarize — get a quick overview of a document's contents without opening it
Ask questions — query a document's content right from the file system

This means you no longer need to open Word, Excel, or PowerPoint to get a summary or find specific information inside a file. For anyone who deals with large volumes of documents, this is a meaningful time saver.
