The security updates also eliminate 118 vulnerabilities, 17 of which are critical and two 0-day vulnerabilities. Below is a compact overview of these updates released on patchday.


A list of the updates can be found on this Microsoft page. Details about the update packages for Windows, Office, etc. are available in separate blog posts.

Notes on the updates

Windows 10 version 20H2 to 21H2 use a common core and have an identical set of system files. Therefore, the same security update will be delivered for these Windows 10 versions. Information on enabling the features of Windows 10, which is done through an Enablement Package update, can be found in this Techcommunity post. Windows 10 20H2 and Windows Server 20H2 will receive updates for the last time.

All Windows 10 updates are cumulative. The monthly patchday update contains all security fixes for Windows 10 and all non-security fixes until patchday. In addition to vulnerability security patches, the updates include security improvement measures. Microsoft is integrating the Servicing Stack Updates (SSUs) into the Latest Cumulative Updates (LCUs) for newer versions of Windows 10. A list of the latest SSUs can be found at ADV990001 (although the list is not always up to date).

Windows 7 SP1 is no longer supported as of January 2020. Only customers with a 3rd year ESU license (or bypass measures) will still receive updates. With the current ESU bypass lets install the update. Updates can also be downloaded from the Microsoft Update Catalog. Updates for Windows RT 8.1 and Microsoft Office RT are only available through Windows Update.
