Windows 10: After KB4495620 Windows Update, Network is not working

Hello ,


Today I have got an Windows Update - KB4495620 (Cumulative Update for .NET framework 3.5 & 4.8). After installing that, my network is broken. It shows as broken as shown in the attachment. It's partially working when I connect my laptop with LAN, my chrome and other things expect Microsoft products (Edge, Outlook) showing me as offline. And I'm seeing an error in windows update page after the page. I tried creating the Windows 10 image of my machine using MediaCreation tool and reinstalled windows. Again the same windows update got installed and again the same issue!

Someone who have faced this or someone who has idea on this, please let me know! Any help or any information related to this will be much helpful.


I'm using HP AU627-TX Laptop running Windows 10 Home.

Provided all the screenshots for reference below! Thanks in advance!


1. Update which I have received



2. After the update and system restart the error I'm getting on network page (wifi itself not showing)




3. Post update -> Windows Update section throwing this error


4. After this update, Wifi itself its now showing

Another question, is this on a home network or a work network? The steps @eidairaman1 listed are always a good first step. If this is on a work network you manage, I'd be much more concerned than the home one. It is possible someone is screwing with you, but malware could also be the culprit.

Since none of the troubleshooting steps here worked, I'd suggest you do a Clean install.

How to Dump Networking Parameters?


Had a customer with this problem, they had a brand new Dell Optiplex 3050, with Windows 10 1709, and Realtek Gbit Family of lan adapters (wired connection). After much troubleshooting (many suggestions listed in the course of this thread), it turned out the PC needed a bios update. Among the updates listed on the dell website for bios version 1.52 (I flashed it with the latest 1.92) was "Update RealtekLOM".

LOM is "lan on motherboard" and the Realtek has flashable firmware.

One step for others having this issue is to check their computer manufacturer's website for "Lom" firmware updates for the particular network adapter - whether integrated or an add-in.
