UPDATE 10/22: Windows 10 Insider Preview Beta and RP Channel Build 19042.608 (20H2)

Hello Windows Insiders, today we’re releasing 20H2 Build 19042.572 (KB4579311) to the Beta and Release Preview Channels for those Windows Insiders who are on 20H2 (Windows 10 October 2020 Update). This update includes the following fixes and improvements:

• We fixed an issue with a possible elevation of privilege in win32k.
• We fixed an issue with the Group Policy service that might recursively delete critical files in alphabetic order from %systemroot%\systm32. This issue occurs when a policy has been configured to delete cached profiles. These file deletions might cause stop error “0x5A (CRITICAL_SERVICE_FAILED)” boot failures.
• We fixed an issue with creating null ports using the user interface.
• Security updates to Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Media, Windows Fundamentals, Windows Authentication, Windows Virtualization, and Windows Kernel.

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

Thanks,
BLB
