copilot chat update

The copilot chat update tag covers Microsoft 365 Copilot Chat changes that expand how the assistant works with workplace documents. The featured June 2026 rollout allows Copilot to ground answers in images embedded in Word documents, PowerPoint presentations, and PDFs on desktop for worldwide commercial tenants. This matters because useful information often appears in screenshots, diagrams, charts, and slide visuals rather than searchable text. Coverage here focuses on what the update means for Windows users and enterprise IT teams, including the practical value of image-aware answers in everyday Microsoft 365 workflows and how well the feature handles real-world documents.
