2020-09-08 15:35

Windows Update

Today is the second Tuesday of September 2020 and important security updates/cumulative or 'B' updates are now available for all supported versions of Windows 10. As always, the updates are available for installation when you check for updates in the Settings and click on 'Download and install now' button.

Like every Patch Tuesday release, the cumulative update comes with security fixes and general bug fixes, and the patch is rolling out to PCs with May 2020 Update, November 2019 Update, May 2019 Update and later.

Below is the list of all new updates for Windows 10:

To install the patch, head to the Settings app and click on the Windows Update option to install the patches. If you own multiple PCs or if you would like to patch the PCs manually, you can learn more about it here.

Build 19041.508 for version 2004

The first cumulative update for Windows 10, version 2004 is KB 571756 and it comes with these fixes:

  • 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 Ensuring clients stay secure, changes to scans against Windows Server Update Service (WSUS) servers.
  • 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.
  • 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.
