Windows 10: Possible issue with KB4566782 where it breaks Automatic driver update in Device Manager

Hi, I would like to report a potential bug/issue with August 11, 2020—KB4566782 OS Build 19041.450

https://support.microsoft.com/en-us/help/4566782/windows-10-update-kb4566782


I'm using Windows 10 build 2004.

Installing this update kb4566782" caused "Automatic driver update" functionality in device manager mmc plug-in to break.


Describing the problem behavior after kb4566782 is installed:

Within device manager , either in computer management or standalone devmgmt.msc, select any device - right click - update driver - search automatically for drivers - the wizard DOES NOT go to"Searching online for drivers..." stage and comes back with the status "You are already using the best driver..." within 1 second.

I used procmon/process explorer to compare this behavior to 2 known working instances :

A July07, image from same machine, and another machine running build 1909; And in both these cases, mmc.exe hosting device manager is showing making calls through wininet.dll to discover proxy, IE zones and finally going out to the network.

While in broken instance, no calls to wininet.dll are made. Process explorer confirms that wininet.dll is NOT loaded on device manager launch on the broken instance, while it is in both working instances. I uninstalled/reinstalled the kb4566782 twice to confirm, and was able to reproduce the issue.

Note: this behavior is exhibited only within device manager, other apps/processes continue to load wininet.dll as expected.

Additional finding: Attempting to repair through DISM or sfc commands does not work.

The only recoruse is to either uninstall the update, or to revert to an earlier image.

As well as in some cases, device manager might disappear altogether from computer management after kb4566782, though standalone devmgmt.msc still loads the mmc console. But the above issue with driver update is still exhibited.

device manager drivers/update/fix help

I need help with my drivers as they aren't showing up right in Device manager. I have double or triple entries in some of the categories; I have provided a link or file so that you can see what mine looks like. If anyone could direct me in the right path that would be awesome! I think the reason for my mouse studders/issues and also performance issues in the many games that I play is the reason behind these Drivers. Below is a image that I captured with gyazo that lists my devices.

-BenQ XL2420Z 144hz
-Logitech G403 Prodigy
-Corsair Vengeance K95

-When I fix the drivers that I need will the grayed out devices fix themselves/disappear in Device manager? Also, if/when I get my drivers all squared away and updated.. let's say I have some grayed out devices that are still in those sections.. is it OK to uninstall those or not?

-I also don't have any idea what those Microsoft streaming devices in Sound are!??! Could it be something I need to turn off in BIOS or?

-Lastly, what's the deal with the WAN Miniports?


Thank-you!
