Cumulative Update KB4528760 raises the OS build to 18362.592 (Windows 10 V1903) or 18363.592 (Windows 10 V1909). The update is available for Windows 10 version 1903, for Windows 10 version 1909, and for Windows Server version 1903 and Windows Server version 1909. It contains quality improvements but no new operating system features. Here is the list of improvements, referred to by Microsoft as highlights:

  • Updates to improve security when storing and managing files.
  • Updates to improve security when using input devices such as a mouse, keyboard, or stylus.

The following fixes and improvements to Windows 10 version 1909, which are identical to version 1903 (update is also available for the Hololens), have been added:

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.

Thus, a number of unspecified errors are fixed (this included also the bug in the CryptoAPI). 

Microsoft has also released an update directly for the Windows Update Client to improve its reliability. This is rolled out outside of Windows Update if the machine is compatible and not an LTSC variant and updates have not been blocked by GPO.

This update is automatically downloaded and installed by Windows Update and is also available in the Microsoft Update Catalog and via WSUS. Microsoft strongly recommends that you install the latest service stack update (SSU) for your operating system before you install the latest cumulative update (LCU). Microsoft does not report any known issues with this update.

      Imho not possible to install such an old update. But give it a try – download the KB from Microsoft Update Catalog and check, if you can install it manually.
