How to close all open tabs in Win11 Notepad at once?

Closing all open tabs in Windows 11 Notepad at once is not a built-in function of the application itself, as the current version of Notepad lacks a dedicated "Close All" command in its tab context menu or file menu. The most direct method is to close the entire Notepad application window, which will prompt you to save any unsaved changes across all open tabs before terminating the entire session and closing every tab simultaneously. This approach leverages the application's exit protocol as a de facto "close all" mechanism, making it the only native, single-action solution available within the software's standard interface.

The absence of a specific "Close All Tabs" button or shortcut reflects Notepad's relatively recent and minimalist implementation of tabbed interfaces, which was introduced as a modern update to a historically simple text editor. Unlike more advanced code editors or word processors that manage extensive workspaces, Notepad's tab system is designed for lightweight use, where the expectation is typically to handle a limited number of files. Consequently, the workflow for mass-closing tabs is routed through the application's exit routine. Users must rely on the system prompt that appears upon closing the window, which aggregates save decisions for each modified document, thereby providing a consolidated control point for managing all open files.

For users seeking a method that avoids closing the entire application window, a manual workaround exists but requires multiple actions: you must right-click on each tab individually and select "Close" from the context menu, which is inefficient for a large number of tabs. There is no official keyboard shortcut, such as Ctrl+Shift+W commonly found in browsers, to close all tabs in Notepad. This limitation means that if you wish to keep the Notepad application running while clearing all tabs, you are left with no programmatic option and must resort to the manual tab-by-tab process or accept restarting the application.

The practical implication is that users managing many simultaneous text files in Notepad must plan their workflow around this constraint, either by grouping work sessions to be concluded together or by considering alternative text editors that offer more robust tab management features if this functionality is critical. The design choice underscores Notepad's continued positioning as a basic, streamlined tool within the Windows ecosystem, where advanced multi-document management is intentionally outside its scope. For now, the definitive way to close all tabs at once remains the application-level exit command, with all other methods being iterative and less efficient.
