📢 Microsoft releases Windows 10 build 19042.508 (v.20H2) to Windows Insiders in the Beta channel

Microsoft releases a new test build of Windows 10 to the insiders in the Beta channel (formerly known as Slow Ring). The new insiders preview build 19042.508 (KB4571756) is intended for commercial customers in the Beta Channel and Release Preview Channel for pre-release validation as outlined here.

The new build doesn't include any new features, but a set of quality improvements as security updates. To see what are the changes in this build for Windows 10 version 20H2, continue reading further.

As stated by Microsoft in the Release Notes, the latest Windows 10 build 19042.508 (KB4571756) for version 20H2 includes the following quality improvements:

• Microsoft fixed an issue with a possible elevation of privilege in windowmanagement.dll.
  
  
• Microsoft fixed 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.
  
  
• 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, and the Microsoft JET Database Engine.
