[German]Microsoft has released the cumulative update KB4580364 for Windows 10 Version 2004 and 20H2 on October 29, 2020. This update had been tested with Windows insiders for one week (see Windows 10 20H2/2004: Update KB4580364 (19042.608) released for Insider)).
Blog reader EP has given a hint about that update release (thanks). 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, please check the Microsoft Update Catalog for Servicing Stack Updates).
Important: From July 2020 all Windows updates disable the RemoteFX vGPU features 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.
