[German]On October 13, 2020 (second Tuesday of the month, Patchday at Microsoft) several cumulative updates for the supported Windows 10 builds were released. Here are some details about the respective updates.

A list of the updates can be found on this Microsoft website. I have pulled out 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, please check the Microsoft Update Catalog 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 the Windows 10 version 2004 released in May 2020, Microsoft provides the following update packages.
Update KB4579311 for Windows 10 Version 2004
Cumulative Update KB4579311 raises the OS build to 19041.572. 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:
- Updates to improve security when using Microsoft Office products.
- Updates for verifying usernames and passwords.
- Updates to improve security when Windows performs basic operations.
The following fixes and improvements are added:
- Addresses an issue with a possible elevation of privilege in win32k.
- Addresses an issue with the Group Policy service that might recursively delete critical files in alphabetic order from %systemroot%\system32. This issue occurs when a policy has been configured to delete cached profiles. These file deletions might cause stop error "0x5A (CRITICAL_SERVICE_FAILED)" boot failures.
- Addresses an issue with creating null ports using the user interface.
- Security updates to Windows App Platform and Frameworks, Microsoft Graphics Component, Windows Media, Windows Fundamentals, Windows Authentication, Windows Virtualization, and Windows Kernel.
This update is automatically downloaded and installed by Windows Update. This update is also available in the Microsoft Update Catalog und and via WSUS. Microsoft strongly recommends that you install the latest service stack update (SSU) KB4577266 for your operating system before you install the latest cumulative update (LCU). Actually, the SSU should already be integrated in the cumulative update – either the KB articles have not yet been updated in this respect, or the integration has not yet been done.

For the update, Microsoft states that 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 it tries to drag with the mouse. For details, see KB4564002.
Second problem: When you install a third-party driver, you may receive the error message "Windows cannot verify the publisher of this driver software". When you try to view the signature properties using Windows Explorer, you may also receive the error "There was no signature in subject".
This problem occurs if Windows validation identifies an incorrectly formatted catalog file. Starting with this release, Windows will require the validity of DER-encoded PKCS#7 content in catalog files. Catalog files must be signed according to Section 11.6 of the description of DER encoding for SET OF members in X.690. In this case you should contact the driver manufacturer or device manufacturer (OEM) and ask them for an updated driver to resolve the problem.
Note: This update is also available for the Insider Preview of Windows 10 20H2, as this version shares updates with version 2004.
Microsoft has also released an update directly to 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.
Updates for Windows 10 Version 190x
Microsoft provides the same update packages for the Windows 10 builds 1903 and 1909. The following updates are available for the Windows 10 May 2019 Update (Version 1903) and the Windows 10 November 2019 Update (Version 1909).

A major point of cumulative updates is that responsibility for the completeness of content is Microsoft's. Windows 10 users, many of whom are not deeply knowledgeable of Windows 10 because they are using what to them is a consumer product, should not be expected to be alert for possible exclusions, like service stack updates, from cumulative updates.
Microsoft seems generally unsympathetic about the understandable lack of expertise of many of its home Windows 10 users.
This month's cumulative updates for Windows 10 versions 1909 (KB4577671) and 2004 (KB4579311) must be very large ones because download and installation times are a lot longer than usual, especially for 2004. I guess that this also applies to earlier feature updates.
What happened to "Feature update to Windows 10 (business edition), version 1909".
It has expired? why?
I see that MS updated (as of sept 2020) ISO images for Win10 b1909 and b2004…
