A family of Microsoft word processing software products for creating web, email, and print documents.
On Word for Mac there is no documented setting in the provided material that controls whether each document opens full screen or at the last-used window size. The available Word for Mac guidance in the context only covers crash/performance issues and specific feature toggles (such as Copilot), not window sizing behavior.
Because of that, no supported, documented method can be given here—such as a preference, registry/PLIST reset, or template change—to stop Word from opening documents in a full-screen window on macOS.
