The update has resolved an issue associated with a possible elevation of privilege in Win32K.

Microsoft has resolved an issue associated with the Group Policy service, which might recursively delete critical files in alphabetic order from %systemroot%\system32. The problem occurs when a policy has been configured to delete cached profiles. You should note that the file deletions might cause 0x5A (CRITICAL_SERVICE_FAILED) stop error boot failures.

Microsoft also released a cumulative update for Windows 10 Version Next 20231.1005 with KB4586238 for Windows Insiders in the Dev channel. Microsoft tweeted that they are rolling out a small update to validate their servicing pipeline in the Dev Channel.
