Improvements and fixes

This security update includes quality improvements. Key changes include:

  • Addresses an issue that causes certain applications to stop responding when under load if they rely on the JScript Scripting Engine. 
  • Addresses an issue that prevents you from installing some .msi apps. This occurs when a device is managed by a Group Policy that redirects the AppData folder to a network folder. 
  • Addresses an issue in Universal Windows Platform (UWP) apps that allows single sign-on authentication when an app does not have the Enterprise Authentication capability. With the release of CVE-2020-1509, UWP applications might begin prompting the user for credentials. 
  • Security updates to Internet Explorer, the Microsoft Scripting Engine, Windows Graphics, Windows Media, Windows Shell, the Windows Wallet Service, Microsoft Edge Legacy, Windows Cloud Infrastructure, Windows AI Platform, Windows Fundamentals, Windows Kernel, Windows Core Networking, Windows Storage and Filesystems, Windows Hybrid Storage Services, 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.

For more information about the resolved security vulnerabilities, please refer to the Security Update Guide.
