Updates complete up to 96% then fails

Update KB3078071 fails

I have the dreaded "Windows cannot complete the update process. Undoing changes." I've tried going to the page where Microsoft has the update fix. https://support.microsoft.com/en-us/gp/windows-update-issues/en-us That doesn't help. I've tried searching for answers on Google and here, but I'm not finding any particular error. It just "fails". Looking at the update history provides nothing useful. It just says that the updates failed with a generic error code, so I can't figure out which update is causing the problem. Because of Windows's intelligent update system, this means that NOTHING gets updated because apparently if it fails on one update, Windows removes the failed updates AND all the non-failed updates.

Now that they've all been downloaded to my computer, I can't figure out how to install them one at a time to figure this out. Does anyone else know? If they weren't downloaded yet, I could just do them one at a time. But apparently they are already on my computer somewhere. I need to delete them and install them one at a time.

(Interesting note - I notice that the first fail was a "Windows 10 Home" update back on July 28th. I haven't made my computer eligible for the free upgrade yet, so I'm not sure what that's all about. Then every few days, I'll get the same Windows 10 update error. I'm assuming it's failing because I've elected NOT to install it yet. Those are the only errors until about 3 days ago. Now MOST updates fail, including security and misc. updates, but not all.)

BTW - I tried deleting the software distribution folder to no avail.

It's update KB3078071. It's the cumulative update for IE11 and some other things. Apparently this creates an issue so bad that when you try to install it with other updates at the same time it causes them all to fail. This is apparently a semi-widespread issue that Microsoft has yet to address. This update was released only 5 days ago, and I have no information on how widespread the problem may be. Apparently, not everyone is having a problem with it.

I had no problem with this update, even though I installed it with almost every other update that was available.

This is actually the first time that I've ever had Windows 8 screw up on an update. I became so confident that I actually started letting Windows automate the whole process. This went on for a couple of years until this happened. So to the defense of Microsoft, I think this may be one of the things that they've actually done right. There's just something about my particular machine that's causing a conflict. I'll just have to keep checking Google to see if there is ever a solution.

EDIT - I just tried downloading the update manually (Microsoft website direct download) and it still failed. Apparently this file is an IE11 security 'cumulative' update, which will not really affect me anyway because I don't use IE. However, the update mentions something along the lines of '....and some other things', so I don't really know what's all supposed to be there. Maybe when the next security update is released for IE11 it will go away. Or, I may just decide to install 10 soon anyway.
