Microsoft is revamping the delivery of updates for Windows 11 by bundling updates for essential components like .NET, drivers, and firmware with the monthly update cycle, currently in testing. The latest preview build (26300.8687) includes improvements to default applications, particularly the Calculator app, which will enhance readability in high contrast themes and fix inaccuracies in square-root calculations. Users will also have the option to delay monthly updates indefinitely to address concerns about update installation failures.
