Windows 7: 800B0100: Windows Encountered an unknown error HP p6-2022uk

Hey guys, first post on this forum! I've seen so many helpful people on these so fingers crossed I can get my problem sorted.

Basically, my HP Desktop P6-2022uk hasn't been able to search for (and hence download) updates, and I'm getting the error code 800B0100 which I'm more than familiar with. This has been doing it for a year and a half, give or take a month or 2.

I've ran the Download System Update Readiness Tool for Windows 7 but it doesn't help.

I also ran the "sfc /scannow" and got "Windows Resource Protection did not find any integrity violations" at the end.

Massive thanks in advance, I really appreciate the help!

Here's the list of errors that CheckSUR found and couldn't fix...

I'll post a fix protocol later.

I've uploaded a file - jb6aa.zip - to my OneDrive at Noel's OneDrive
Please download and save it.
Right-click on the downloaded file, and select Extract all…
Extract to the default location - which will create a new folder jb6aa in the same place.
Open this folder - there should be two folders inside it (Manifests, and Packages)

Copy the content of the Packages folder to the folder
C:\Windows\Temp\CheckSur\Servicing\Packages

And the content of the manifests folder (.manifest files) into this folder:

C:\Windows\Temp\CheckSur\Winsxs\Manifests

Now run the CheckSUR tool again (it may take a while)

Post the new CheckSUR.log file, and the CheckSUR.persist.log file.

Nope - I'm having connectivity problems this evening, so it may be taking some time to upload. Please wait for jb6aa.zip to become available.
