Microsoft Windows Security Updates October 2018 release overview

Microsoft released security updates for all versions of Microsoft Windows, Microsoft Office, and other company products on the October 2018 Patch Day.

October has been quite the busy month for Microsoft so far. The company released the October 2018 Update for Windows 10 on October 2 but had to pause the distribution after user reports emerged that user files could be deleted during the upgrade to the new version.

Microsoft addressed the issue, or part of it, in KB4464330 for Windows 10 version 1809 it seems. The company has not updated the KB article for Windows 10 version 1809 so it is possible that the issue is not fixed fully.

The detailed overview provides system administrators and home users with information about released updates, known issues, links to support pages and other resources, and download instructions.

Note: We recommend to create backups of any system that you want to install updates. While updates usually install fine, last year has shown that updates may break things or delete important apps or files.
