Microsoft has just released a new preview version of Windows 10 for Insiders subscribed to the Beta and Release Preview channels.
Windows 10 is now in build 19042.572 and this is done with a simple cumulative update (KB4579311). Obviously the update only comes with performance improvements and bug fixes with no new features at all.
The update was released via Patch Tuesday, so it also contains security fixes. Microsoft says it has fixed a bug that allowed win32k privileges to be changed. It also fixes an error that affects how null ports are created in the user interface.
Additionally, this release includes "security updates for Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Media, Windows Fundamentals, Windows Authentication, Windows Virtualization, and Windows Kernel," as stated by Microsoft.
But there are also improvements to the political group service:
"It simply came to our notice then political group service which may delete critical files in alphabetical order from% systemroot% \ systm32. This issue occurs when a policy is deleted for deleting cached profiles. "These file deletions may cause a '0x5A (CRITICAL_SERVICE_FAILED)' shutdown error and startup failures," Redmond said.
The Windows 10 October 2020 Update, called version 20H2, has already reached the final development stage and Microsoft has sent the final version to Windows Insider users.
As for the availability of the update to everyone, it is possible that it will be released later this month, but it will happen gradually, as it is a service pack with small improvements.
