Close All Windows, also known as CloseAll, is a lightweight task-management utility developed by NTWind Software. It lets users close several running applications at once instead of closing every window manually. The program sends a standard close signal, allowing supported applications to display save prompts for unsaved work.
Close All Windows is useful for office workers, developers, multitaskers, and anyone who regularly works with many open programs. Users can select specific applications, group or sort windows, search by application name, and run the closing task silently. For additional controls such as transparency and always-on-top mode, explore WindowTop Pro.
