[German]On December 14, Microsoft released security updates for Windows clients and servers, for Office etc. – as well as for other products (but not for Exchange) – were released. 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 2004 through 21H2 share 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 version 1909 as well as 20H2, 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 through 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 10 2004 will get updates for the last time.
Windows 7 SP1 will no longer be supported as of January 2020. Only customers with a 2nd year ESU license (or bypasses) will still get 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.
