It looks like Microsoft is working on a new feature for Windows 11 that will allow users to configure the behavior of apps when they first open. Right now, pretty much all Windows app will open in windowed mode, until manually set to open maximized by the user. But in the latest Windows 11 preview builds, a new option has been discovered that changes this.
First spotted by phantomofearth, the new option appears in the accessibility area of Windows Settings. The option reads: "Automatically open app windows maximized when they open" with the ability to toggle it on or off. When enabled, all Windows apps will opened in a maximized state by default, meaning the user will no longer be forced to do so for every app they open.
