Update highlights:

  • Updates to improve security when Windows performs basic operations.
  • Updates to improve security when using input devices (such as a mouse, keyboard, or pen).
  • Updates to improve security when using Microsoft Office products.

All improvements and fixes:

This security update includes quality improvements. Key changes include:

  • 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, the Microsoft Scripting Engine, and the Microsoft JET Database Engine.
