As part of September’s patch Tuesday Microsoft have updated Windows 10 May 2020. KB4571756 takes the build to build 19041.508 and includes the same fixes as the 20H2 update released yesterday. 20H2 and 20H1 share the same codebase which is why they have the same set of updates:

Highlights

Updates to improve security when using input devices (such as a mouse, keyboard, or pen).

Updates to improve security when Windows performs basic operations.

Updates for storing and managing files.

Updates to improve security when using Microsoft Office products.

Improvements and fixes

This security update includes quality improvements. Key changes include:

Addresses an issue with a possible elevation of privilege in windowmanagement.dll.

Addresses a security vulnerability issue with user proxies and HTTP-based intranet servers. After installing this update, HTTP-based intranet servers cannot leverage a user proxy by default to detect updates. Scans using these servers will fail if the clients do not have a configured system proxy. If you must leverage a user proxy, you must configure the behavior using the Windows Update policy “Allow user proxy to be used as a fallback if detection using system proxy fails.” This change does not affect customers who secure their Windows Server Update Services (WSUS) servers with the Transport Layer Security (TLS) or Secure Sockets Layer (SSL) protocols. For more information, see Improving security for devices receiving updates via WSUS.

Security updates to Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Input and Composition, Windows Media, Windows Shell, Windows Cloud Infrastructure, Windows Fundamentals, Windows Management, Windows Kernel, Windows Virtualization, Windows Storage and Filesystems, the Microsoft Scripting Engine, and the Microsoft JET Database Engine.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
