Thank you!! Resetting my router multiple times didn’t work, yet following your steps of opening up the Admin Command Prompt, typing Netsh Winsock Reset and restarting got my Internet connection back and on full bars!! Really glad I found your site, bookmarked! 
Hi
Based on what I already had, I added something else to produce netfix.bat (I’m one of the et al). Maybe I can get A - F added.

This is also fixed easily (if using ethernet, as I haven’t tried wireless).
Step 1. Go into your Network Options
Step 2. Disable your Ethernet Adapter
Step 3. Enable your Ethernet Adapter
I think the problem lies with your modem/router sending the proxy settings to your PC and your PC unable to read the instructions. Not exactly sure, I just know this just worked for me.
Source: Used to work with networking for a while.
FIX THAT WORKED FOR ME!!! I read a comment somewhere and i can’t find it anymore but you want to EXPORT the registry entries for Winsock and Winsock2 from a working machine and install it onto yours. Delete the keys from your computer, then install the ones you got from the working machine. I tried every fix there is and this is the only one that worked for me.
Jesus, Mother, Joseph & Buddha after trying almost everything, finally I have networking totally up and running. THANK YOU!!! (I wasn’t even going to try what you said but I was desperate and since it seems that the IPv6 has always been in an issue in some form, I tried it.) (~_~)
Did you follow all the methods listed in this guide?
My boss are encounting this problem. He asked me to help him. I am looking for the solutions. Hope i can make it this evening, otherwise my boss will look down me…
I experienced the same problem and tried several of the solutions as described above but had no results. Then I noticed that a second PC had the same problem. The one thing the PCs had in common was the router (Fritz!Box). I switched off the router for about a minute and switched it on again. Problem solved!!
Hi Kevin, i did it both with Paths (as written above) and with Patchs (as you wrote in the comment) - but the ‘blocked by group policy error’ still appears. Any tips? thanks
I had missing protocol message after upgrading to windows 10 but the ‘netsh winsock reset’ worked a treat 2min fix worked first time thank you
You can right click and create the keys.
This is how it shows it by default. Therefore, you’re good. No need to make any changes.
Hi Kevin. I’ve tried all of these solutions but nothing works. I’ve been fighting with this issue from 2 months. Do you have any information if Microsoft is working to solve it? Or when they’ll give us a patch or something like this?
