It’s that time of the month again: Windows 10’s Patch Tuesday updates for October are now rolling out. These updates are available for supported versions of Windows 10, including version 2004 and older. As usual, the cumulative updates don’t include any new features, but they do include bug and security fixes.

If you’re running Windows 10 version 2004, you’ll see an update to build 19041.572. Here’s what’s included:

  • Addresses an issue with a possible elevation of privilege in win32k.
  • Addresses 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.
  • Addresses 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.

Those same fixes, oddly enough, are also available for the still-in-testing October 2020 Update. The updates are rolling out to Beta and Release Preview Insiders now.
