Approval modelAuto Review evaluates tool calls and computer actions before they run, with user rules set to Ask first or Allow automatically; Ask first wins when both match. Before actions it cannot undo, such as sending, posting, buying or deleting, a Bot checks for approval; emails go out from draft cards and purchases show an Allow or Deny card. Running commands on the user's own computer defaults to Ask every time.Microsoft says Copilot asks for approval or hands control back before sensitive actions, and users can stop, pause, take control of or delete a task. On Windows, local context and actions are described as working with the user's permission.
