A list of the updates can be found on this Microsoft website. I have extracted the details below. The update installation requires an existing current Servicing Stack Updates (SSUs). Meanwhile, Microsoft publishes an overview of current Servicing Stack Updates (SSUs) under ADV990001 (if it is not up to date, have the Microsoft Update Catalog search for Servicing Stack Updates).

Important: From July 2020 all Windows updates disable the RemoteFX vGPU feature due to the CVE-2020-1036 vulnerability (see also KB4570006). After installing this update, attempts to start virtual machines (VM) with RemoteFX vGPU enabled will fail. More information can be found here.

Updates for Windows 10 Version 2004

For Windows 10 version 2004 that was released in May 2020, Microsoft provides the following update packages.

Update KB4565503 for Windows 10 Version 2004

Cumulative Update KB4565503 raises the OS-Build OS build to 19041.388. The update is available for Windows 10 version 2004 and for Windows Server version 2004. It contains quality improvements but no new operating system features. Here is the list of improvements, called highlights by Microsoft:

  • Improves security in the Microsoft Store.
  • Updates to improve security when using input devices (such as a mouse, keyboard, or stylus).
  • Updates to improve security when Windows performs basic operations.
  • Updates for storing and managing files.
  • Updates an issue that might cause certain games and applications to have visual distortion when resizing in windowed mode or switching from full screen to window mode.
  • Updates to improve security when using Internet Explorer and Microsoft Edge Legacy.
  • Updates an issue that might prevent some applications from printing documents that contain graphics or large files.
  • Updates an issue that might prevent you from connecting to OneDrive using the OneDrive app.

The following fixes and improvements are added

  • Addresses an issue in certain apps that use the ImeMode property to control Input Method Editor (IME) mode in Windows 10, version 2004 (the May 2020 Update). For example, this issue prevents input mode from automatically switching to Kanji or Hiragana. For more information, see KB4564002 and the blog post, Getting the May 2020 Update Ready for Release – UPDATED.
  • Addresses an issue that might prevent you from using PowerShell to change the system locale on Server Core platforms.
  • Addresses an issue that might cause certain games and applications to have visual distortion when resizing in windowed mode or switching from full screen to window mode.

  • Addresses an issue that might prevent some applications from printing documents that contain graphics or large files after installing Windows Updates released June 9, 2020.
  • Addresses an issue that might prevent you from connecting to OneDrive using the OneDrive app. This issue occurs on some older devices or on devices that have older apps, which use legacy file system filter drivers. As a result, this might prevent these devices from downloading new files or opening previously synced or downloaded files.
  • Security updates to the Microsoft Scripting Engine, Windows App Platform and Frameworks, the Microsoft Store, Windows Graphics, Windows Input and Composition, Windows Media, Windows Shell, Windows Fundamentals, Windows Management, Windows Kernel, Windows Hybrid Cloud Networking, Windows Storage and Filesystems, Windows Update Stack, Windows MSXML, Windows File Server and Clustering, Windows Remote Desktop, Internet Explorer, Microsoft Edge Legacy, and the Microsoft JET Database Engine.

This update is automatically downloaded and installed by Windows Update. This update is also available in the icrosoft Update Catalog nd via WSUS. Microsoft strongly recommends that you install the latest service stack update (SSU) KB4566785  for your operating system before you install the latest cumulative update (LCU).

It is especially important to install SSU KB4566785  because it does not just perform quality improvements to the service stack. This update also fixes an elevation of privilege vulnerability CVE-2020-1346  in the Windows Modules Installer.

For this update, Microsoft states that when you use some applications, such as Microsoft Excel, users of the Microsoft Input Method Editor (IME) for Chinese and Japanese may receive an error, or the application may stop responding or close when they try to drag the mouse.

    Microsoft has known about the SSD trim scheduling problem for 6 months but has not even yet deigned to fix it. Additional features come first and reliability a distant second in the Nadella era. New features are irrelevant to most users. They need and want RELIABILITY but Microsoft seems gripped by some psychosis compelling it to neglect reliability in favour of its features fetish.
