Windows 10 Version 2004: Update KB4576754

[German]A note about update KB4576754, which seems to be distributed on begin of September 2020 on some systems with Windows 10 version 2004. A blog reader asked me about it because he could not find any information about it.

A reader is wondering about update KB4576754

Blog reader Matthias T. contacted me by mail late yesterday evening and asked for the update KB4576754, which he is offered. Matthias wrote:

Since today I find an update on my Win 10 Enterprise 2004 system called "2020-08 Microsoft Edge Update for Windows 10 Version 2004 for x64-based systems (KB4576754)". It has already been downloaded automatically and is now waiting for installation.

But neither a Google search nor a search on the Windows pages was successful.

I have never had anything like this before. At least at Microsoft the KB numbers were visible. Either I am the first in the world with this update or what kind of a prank is this again?

Maybe you could do something with it and help.

Since the topic is of interest for more people, I took it up here in my blog.

What is update KB4576754?

Update KB4576754 seems to have somehow released unintentionally by Microsoft. It is  offered to Windows 10 Version 2004 users as a forced update to the Chromium Edge browser. In tensformum there is this post:

Ok, just now I checked Windows Update and under a different KB number I got MS Edge Chromium, forced on me again.

[…]

THEN, MS threw another curve ball. Every time I check for Updates…that same Edge Chromium is force installed again. It's now KB4576574. So, I removed it again… and ofc, every time I check for Updates it's back again.

This is an update for the Chromium Edge Browser, but it hasn't been officially distributed yet. Only WZOR points this out here, and on this page I found the information that this version was created on August 25, 2020. And in this forum post someone reports installation errors during the Edge update. I would put it back from installation under Enterprise for now. Anyone else who was offered this update?

Addendum: Update KB4576574 was distributed on August 31, 2020, shortly before the updated package KB4562830 has been released. This is the update for the current Edge 84.0.522.52, for those who had the Edge installed as V81 but was not up to date. Or had not yet installed it under Win 10 2004. The "new" Edge is then part of the new KB4562830 as a feature update to the 20H2.

Addendum 2: Microsoft released a KB-Article für Update KB4576574 (Update for the new Microsoft Edge for Windows 10, version 1809, 1903, 1909, and 2004: August 31, 2020) that contains more details.
