Windows 10 update history tracker

Windows 10 update history information helps you know exactly what's the latest version of Windows 10 available.

UPDATED 10/19: Windows 10 can receive different kinds of updates, including “quality updates” and “feature updates” to patch security vulnerabilities, fix bugs and reliability problems, improve system performance, and introduce new features. Since updates can be confusing and difficult to track, in this guide, you’ll understand the different between the quality and feature updates, and more importantly, you’ll find the history of every Windows 10 update grouped by releases with information, such as build and knowledge base (KB) number, release date and number, and platform to help you stay inform.

Quality updates (also referred as “cumulative updates”) are those updates that Windows 10 downloads and installs every month automatically through Windows Update. These updates are cumulative and include the new fixes and improvements as well as the previously available patches. Usually, Microsoft releases these updates every second Tuesday of the month, which rollout date referred as “Patch Tuesday” or “Update Tuesday.” Also, internally, these updates are known as the “B” release, because they roll out during the second week of the month. The Windows 10 updates include security fixes and non-security fixes.

In addition to the B release, Microsoft also pushes two more updates known as “C” and “D” releases during the third and fourth week of the month. These cumulative updates are optional and contain non-security fixes that the company is still testing and planning to release in the next Patch Tuesday update (the following month).

The company also provides updates outside of the regular schedule, and they’re referred to as “on-demand updates”. Typically, these are emergency releases that contain fixes that can’t wait to the next update for Windows 10.

Feature updates are released twice a year and they are technically new versions of Windows 10 (For example, Windows 10 version 20H2). Unlike quality updates, they include new features and improvements, and they require full reinstallation. However, reinstallation depends on the version your device is running and the update you’re trying to install. In the past, upgrade was required regardless of the version on your device, but then the company shifted to a “major” and “minor” releases, meaning that the first feature update of the year is consider major and requires reinstallation, while the second semi-annual update is consider minor and applies as a quick regular update if you have the first semi-annual update already installed. Otherwise, the upgrade process doesn’t change.

Also, these new versions of Windows 10 are optional, meaning that they don’t install automatically until you trigger the process manually through Windows Update. However, if you’re running a version nearing the end of service, then the update will install automatically.

Microsoft makes available the first semi-annual feature update during the spring (April or May) and the second one during fall time (October or November).

To help you stay up to date, here is the latest Windows 10 update history information. If you want to check what updates are already installed on your device, use these instructions. The history for Insider builds have been relocated to this page.
