Microsoft released their October 2020 security update on October 13th, and it includes several improvements, corrections and changes to the Windows system.

 

Listed below are some of the key changes in the update:

 

  • Adding notifications to Internet Explorer 11 that informs users about the end of support for Adobe Flash coming in December 2020

  • Allowing administrators to disable Jscript in specific security zones

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

  • Updates 2021 time zone information for Fiji

  • Addresses an issue with the Group Policy service that might recursively delete critical files in alphabetic order from the system. (This issue occurs when a policy has been configured to delete cached profiles, and these file deletions might cause stop error “0x5A boot failures)

  • Addresses an issue with creating null ports using the UI (user interface)

  • Provides security updates to Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Media, Windows Shell, Windows Cloud Infrastructure, Windows Fundamentals, Windows Authentication, Windows Virtualization, Windows Kernel, and Windows Storage and Filesystems

 

There is also a known issue with this update where, if you install a third-party driver, you may receive an error stating “Windows can’t verify the publisher of this driver software.” You may also receive the error message “No signature was present in the subject” when trying to view the signature properties using Windows Explorer, but Microsoft has provided a workaround for these issues, which is basically just to contact the driver vendor or device manufacturer and ask for an updated driver.
