Microsoft Copilot privacy controls

Microsoft Support, 2026

Read on October 16, 2026

What it is: Microsoft's page on where to find the privacy controls for Copilot, including the setting that decides whether voice conversations are used for model training, and where it sits in the Windows app.
How much weight it carries: Official Microsoft documentation. The page carries a note about a newer app version from August 18, 2026, so the menu paths may already differ on current builds.
