25 failed updates - 800736B3

Hi! Since the beginning of may (May 3rd) every update has failed and they've been stacking up to the point where there's now 25 updates I've missed.

I've googled the issue and tried running "Fixit" and CheckSUR but nothing has helped.
I'm now desperate and annoyed because of all this. That's why I'm coming to you on this forum. You seem to have a lot of knowledge on these topics.

Since I'm new to this, I don't really know which files and logs to attach so if someone explained it to me I'll be able to post them ASAP :)

I am uploading my CBS file to my OneDrive since it is too big to attach here (53MB)

CheckSUR and SFC are clear - but there are some serious errors in your background CBS log.
I'll be honest and say that I have no idea how to fix them ....yet :)

I think your best option for a quick solution is a repair install of Windows.
If you're up for a long and difficult battle to try and work out what's wrong - with a possible repair install at the end anyhow - then I'm willing to give it a go.
Let me know (or ask questions) and I'll try and help.

I did a repair install but encountered error code 80246002 (I believe, I'm not sure) and the update search failed due to an unknown error. Then I tried disabling Norton 360 while searching for updates. It found 150, haha.
I managed to install them all.

But to be on the safe side, can I post the new files tomorrow and can you take a look at if there's still anything there? :)

It sounds a bit scary when said problems were quite serious. Is there anything I should be worried about? Hardware failure etc?

Thanks for your reply, by the way! :)
