Microsoft just released a brand new Windows 10 preview build for users within the Beta and Release Preview channels.

Windows 10 build 19042.572 ships as cumulative update KB4579311, also it obviously comes with only performance improvements and bug fixes with no new features.

Because it lands on a Patch Tuesday, the new build also includes security fixes, with Microsoft saying that it resolved a potential elevation of privilege in the win32k component. At the same time, there's a treatment for an insect affecting how null ports are created with the user interface.

Additionally, this build includes "security updates to Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Media, Windows Fundamentals, Windows Authentication, Windows Virtualization, and Windows Kernel," as Microsoft explains.

And last but not least, there are improvements for the Group Policy service, because the software giant itself says today.

"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," the Redmond-based firm says.
