What's new in Windows 10 Insider Preview Build 19042.450 (20H2)

  • We have fixed 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 the Microsoft Scripting Engine, Internet Explorer, Windows Graphics, Microsoft Graphics Component, Windows Kernel, Windows Input and Composition, Windows Media, Windows Shell, the Windows Wallet Service, Microsoft Edge Legacy, Windows Cloud Infrastructure, Windows Authentication, the Windows AI Platform, Windows Fundamentals, Windows Storage and Filesystems, Windows Update Stack, Windows File Server and Clustering, Windows Hybrid Storage Services, Windows App Platform and Frameworks, the Microsoft JET Database Engine, and Windows SQL components.

The Beta Channel reflects changes that will be included in the upcoming feature release. Builds from this branch work more predictable and stable, but still not intended to serve as your primary operating system.

If you have configured your device to receive updates from the Beta Channel/Slow Ring ring, open Settings - > Update & recovery and click on the Check for Updates button on the right. This will install the latest available Insider Preview of Windows 10.
