Same exact issue - Have gone through all 4 steps and I am still receiving the same errors. Looks like the issue is in on Microsoft's side. Hopefully a fix comes soon.

Hello and thank you very much for the detailed reply. 

Firstly, to answer your questions: The Update Diagnostic Tool I ran was the same one you suggested in your first method. I've run it more than once and seem to receive different results each time. The 2nd last run of it did not fix the same things it has in the past. For example, Service registration is missing or corrupt was not fixed, while Problems installing recent updates was fixed. My last run (during clean boot) fixed nothing.

Secondly, I have not added any new hardware or software. I did burn an audio CD a few days prior to being prompted to install new updates. I had no burning software installed and went ahead and activated Windows Media Player to make the burn. I had not previously used it, so perhaps this installed new components?

I followed your instructions for method 2 and ran Windows Update as described. I am still unable to install the updates. On occasion the updates with get to 11% before crashing. I'm not sure if this is relevant, but felt I should include this information.

As per method 3, I installed and ran the Microsoft Fix It. The application completed and then I searched for updates and attempted to install them once again. The same 12 updates were found. However, I was once again unable to download the updates.

In clean boot, method 4, I searched for updates and was unable to install them. I also ran the Diagnostic Tool again and it was unable to fix anything at all.

What other suggestions do you have?

Thank you!

Hello,

Thank you again for the reply. I ran the Fix It tool to reset Windows Update components. After which I searched for updates and tried to install them. I was unable to do so. The update process reached 11% before crashing to the same error.

I downloaded the System Update Readiness tool from method 2 and installed it. After it successfully installed the hotfix, I attempted to install Windows updates. I am now showing 13 updates. I tried just after installing the hotfix and again after a system reboot. Windows updates continue to fail and can not be installed. I am still getting the same error as in my first post.

I appreciate your help and suggestions. Is there anything else I can try?

11/21/14 -- EDIT

I have just connected to a different network other than my home network and Windows says I have limited connectivity. I am able to browse the Web just fine, and am not sure why it is telling me this. I clicked on the link within the Network Sharing Center to diagnose the problem and I am getting the same error I get with Windows update (0x800706BA). The error window reports that the path of the problem is C:\Windows\diagnostics\system\networking. The source is Engine. 

Does this help to diagnose my issue at all?

Henry I have been tracking your posts since Nov 10 when I started getting the same exact issues. However, I noticed the "limited access" at the very start of my problem. Eleven days in and I can't update windows past 35% download.

Henry I have been tracking your posts since Nov 10 when I started getting the same exact issues. However, I noticed the "limited access" at the very start of my problem. Eleven days in and I can't update windows past 35% download.

I've tried a lot of things to fix this. I wish I had more than a handful of restore points, I'm kind of missing XP right now for that reason. I'm not sure what I am going to do but after the Holidays I may just end up buying Win7 and formatting the HDD. It doesn't seem like I am going to be able to get updates working again based on suggestions I've read and tried so far.

Hi Henry,

Thanks for your update on the issue.

I understand your situation after having tried so many steps. However, the third party firewalls from the security software usually block the connection that hinder the Windows Updates to get installed efficiently.

So, I would suggest you to disable the security software (ESET) installed in your system temporarily, and check if it helps.

Disable antivirus software

http://windows.microsoft.com/en-us/windows/disable-antivirus-software#1TC=windows-7

Disclaimer: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

The above step is worth a try after you come back from holidays and let us know the results for further assistance.

Thank you
