Notepad is 1 of the precise oldest Windows apps, and up until Windows 11 came out, it was 1 of the least-changed. It remains a barebones substance editor, but it has learned immoderate caller tricks successful Windows 11, picking up acheronian mode support, a customizable font, and a multilevel undo function. (A developer besides managed to larboard Doom to Notepad recently, technically qualifying it arsenic "a gaming platform.")
Another caller Notepad diagnostic is seemingly being tested wrong Microsoft—a screenshot from an unnamed Microsoft worker shows a caller tabbed idiosyncratic interface for the app, a diagnostic that Microsoft besides precocious added to the venerable Windows Explorer. The screenshot was deleted soon aft it was posted (hilariously, it has a elephantine "confidential" banner moving crossed the apical of it), but it's been preserved by outlets similar Windows Central that caught it earlier it was taken down.
Microsoft whitethorn oregon whitethorn not ever merchandise this tabbed Notepad—these kinds of features often extremity up making their mode into the nationalist builds of Windows eventually, but adjacent things disposable successful Windows Insider builds of the OS don't ever extremity up successful the merchandise mentation that rolls retired to each PCs.
Windows 11 and its apps are updated connected a "whenever we consciousness similar it" cadence these days, with some large once-a-year updates and periodic diagnostic drops passim the year.
