Windows 10 Cumulative update KB4566116 arrived on 20 August. There are no new amendments in this version but it addresses alot of issues which were found in the previous edition of the “Patch Tuesday”.  Let’s have a look at what KB4566116 has brought with it.

What’s New!

This security update includes quality improvements. The Credit of information written under improvements and fixes goes to the Windows Support Page, Key changes include:

  • Windows 10, versions 1903 and 1909 share a common core operating system and an identical set of system files. As a result, the new features in Windows 10, version 1909 were included in the recent monthly quality update for Windows 10, version 1903 (released October 8, 2019), but are currently in a dormant state. These new features will remain dormant until they are turned on using an enablement package, which is a small, quick-to-install “master switch” that simply activates the Windows 10, version 1909 features.
  • To reflect this change, the release notes for Windows 10, version 1903, and Windows 10, version 1909 will share an update history page. Each release page will contain a list of addressed issues for both the 1903 and 1909 versions. Note that the 1909 version will always contain the fixes for 1903; however, 1903 will not contain the fixes for 1909. This page will provide you with the build numbers for both 1909 and 1903 versions so that it will be easier for support to assist you if you encounter issues.
