WINDOWS 10 KB4528760

KB4528760 applies to Windows 10 version 1903 and version 1909 in addition to Windows Server version 1903 and version 1909.

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.

  • Security updates to Windows App Platform and Frameworks, Windows Input and Composition, Windows Management, Windows Cryptography, Windows Storage and Filesystems, the Microsoft Scripting Engine, and Windows Server.

Then there is the browser certificate in IE and Edge. The NSA discovered the problem but the problem is older after the Lenovo incident and a few others years ago.

It is important to install all updates so that Windows can continue to be as secure as possible in an online world.
