• Windows 10 Insider Preview Beta and RP Channel Build 19042.844 (20H2)
• Windows 10 Insider Preview Beta Channel Build 19043.844 (21H1)

Hello Windows Insiders, today we’re releasing 20H2 Build 19042.804 (KB4601319) to anyone running the Windows 10 October 2020 Update.

This includes Windows Insiders in the Beta and Release Preview Channels who are on 20H2.This security update includes quality improvements. Key changes include:

• We fixed a possible elevation of privilege vulnerability in the win32k component.
• We fixed an issue that might damage the file system of some devices and prevent them from starting up after running chkdsk /f.
• We fixed a security vulnerability by preventing applications that run as a SYSTEM account from printing to “FILE:” ports. To address this issue in the future, make sure your applications or services run as a specific user or service account.
• Security updates to the Windows App Platform and Frameworks, Windows Apps, Windows Input and Composition, Windows Cloud Infrastructure, Windows Management, Windows Authentication, Windows Fundamentals, Windows Cryptography, Windows Virtualization, Windows Core Networking, and Windows Hybrid Cloud Networking.

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

Please note it may take up to an hour after going live for the KB article to show up on the Windows 10 update history page.

Thanks,
BLB
