Microsoft's Windows 10 October 2018 Update, officially released October 2, doesn't offer the standout, marquee features you might have come to expect from earlier releases. But as our review demonstrates, a few new features highlight a longer list of under-the-hood, day-to-day improvements. Our review is based on the final Windows 10 Insider Builds, which led up to the official October 2018 Update. Microsoft doesn't appear to have added anything with the announcement, but we'll check and update this story to reflect any last-minute changes. We've assigned a review score, but, as always, pay less attention to the number than to how the October 2018 Update will affect you.
