Notes on the updates

Windows 10 versions 1903 and 1909 as well as 2004 and 20H2 use a common core and have an identical set of system files. Therefore the same security update is delivered for Windows 10 version 190x and Windows 10 2004/20H2. Information on how to enable the features of Windows 10 version 1909 and 20H2, which is done by an enablement package update, can be found in this Techcommunity article.

All Windows 10 updates are cumulative. The monthly patchday update contains 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 measures to improve security. New Servicing Stack Updates (SSDs) are announced under ADV990001.

Windows 7 SP1 is no longer supported since January 2020. Only customers with an ESU license (or workarounds) will still receive updates. With the current ESU bypass, the update can be installed. 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.

Fixed vulnerabilities

The November 2020 security updates cover 58 vulnerabilities (CVEs) in Microsoft products. Affected are Microsoft Windows, Edge (EdgeHTML-based), ChakraCore, Microsoft Office and Office Services and Web Apps, Exchange Server, Azure DevOps, Microsoft Dynamics, Visual Studio, Azure SDK and Azure Sphere.

Of these 58 patches, 9 are classified as critical, 46 as important and three as moderately serious. A total of 6 of these errors were reported by the ZDI program.
