[German]On March 10, 2020, Microsoft released security updates for Windows clients and servers, for Office, Internet Explorer, etc. Here is a compact overview of these updates.

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.

Servicing Stack Updates

Microsoft now publishes an overview of all current Servicing Stack Updates (SSUs). The list of SSUs can be found at ADV990001 (but is not always up to date).

Notes on the updates

All Windows 10 updates are cumulative. The monthly patchday update includes all security fixes for Windows 10 and all non-security related fixes until the patchday. In addition to the security patches for the vulnerabilities, the updates contain defense-in-depth updates to improve security.

Windows 7 SP1 has been out of support since January 2020. Only customers with an ESU license (or bypass measures) will still receive updates. Updates can also be downloaded from the Microsoft Update Catalog. The updates for Windows RT 8.1 and Microsoft Office RT are only available through Windows Update.

Information about the support period for Windows 10 can be found in the Windows Lifecycle Facts Sheet. The observation described within the blog post Does Windows 10 V1803 Home/Pro still get updates? won't work in March 2020. Blog reader EP has tested it and confirmed it in this comment. KB4540689 for Windows 10 version 1803 can only be installed in Enterprise and Enterprise Education, not in Home and Pro.

The March 2020 security updates cover 115 partially massive vulnerabilities in Microsoft products. 26 fixes are listed as critical, 88 as important and one as moderate. A list of all security updates can be found on the Zero Day Initiative blog. Talos has also published a summary here (details will be covered separately in blog posts).
