Microsoft Security Update Summary (March 8, 2022)

[German]On March 8, 2022, Microsoft released security updates for Windows clients and servers, for Office, etc. – as well as for other products – were released. Below is a compact overview of these updates that were 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 how to enable the features of Windows 10, which is done through an Enablement Package update, can be found in this Techcommunity post.

All Windows 10 updates are cumulative. The monthly Patchday update includes all security fixes for Windows 10 and all non-security fixes up to Patchday. In addition to vulnerability security patches, the updates include security enhancement 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 2nd year ESU license (or workarounds) will still receive updates for the last time in January 2022. For upcoming patches an ESU license for the 3rd year is required. The current ESU bypass allows the update to be installed. Updates can also be downloaded from the Microsoft Update Catalog. The updates for Windows RT 8.1 and Microsoft Office RT are only available via Windows Update.

Fixed vulnerabilities

The March 2022 security updates fix 71 vulnerabilities, three of which are 0-day, in Microsoft products. A list of all covered CVEs can be found on this Microsoft page as well as on this Microsoft page. The colleagues at Bleeping Computer have published an overview of the fixed vulnerabilities here.
