UPDATED 1/11/2024: Microsoft provides different Windows 11, including “quality updates” and “feature updates,” to fix security vulnerabilities, resolve bugs, improve system performance, and deliver new features. Since updates can be challenging to track, this guide will help you understand the difference between quality and feature updates. You’ll also find the history of every update for Windows 11 grouped by releases accompanied by details, such as build and knowledge base (KB) number, release date, and release number.
Windows 11 quality vs. feature update
Quality updates (“cumulative updates”) are those updates that Windows 11 downloads every month through Windows Update. These updates are cumulative and include the new fixes and enhancements and the previously available patches (if the computer needs them).
Typically, Microsoft releases these maintenance updates every second Tuesday of the month. Also referred to as “Patch Tuesday” or “Update Tuesday.” Internally, these updates are known as the “B” release because they roll out during the second week of the month. These types of updates include security fixes and non-security fixes.
In addition to the B release, Microsoft also makes available two more updates, including the “C” and “D” releases that become available in the third and fourth week of the month. These updates are optional and contain non-security fixes expected to arrive in the next Patch Tuesday update. (Starting in April 2023, Windows will receive optional updates during the fourth week of the month. The new schedule replaces the “C” and “D” updates with the “optional non-security preview release.”)
Microsoft also provides updates outside the regular schedule, referred to as “on-demand updates.” Usually, these are emergency releases containing fixes that can’t wait for the next monthly update.
Finally, there are the “optional updates,” which are updates that are not critical but may be necessary for other functionalities. Usually, these updates include packages for Microsoft and non-Microsoft products and third-party drivers (such as printers, cameras, and network adapters).
Feature updates are released once a year, and they represent new versions of Windows 11. Unlike quality updates, they include new features and enhancements and require reinstallation.
Furthermore, these new versions of Windows are optional, meaning that they don’t automatically download and install until you trigger the process manually through Windows Update. However, the upgrade will automatically happen if you have a version nearing the end of service.
Microsoft makes new versions of Windows 11 available during the fall.
Windows 11 current version
Windows 11 version 23H2 is the latest release today. It’s known as the second feature update and has been available since October 31, 2023. The latest quality update is “build 22631.2715.” You can use these instructions to check the version installed on your computer. If you want to determine the quality updates that have already been applied to your computer, use these instructions.
