Update KB2965031 fails

Probably the easiest solution is to uninstall and reinstall MSSE
What error message to you get when you attempt to install the update?

What other Anti-Virus products have EVER been installed on this build?

That may explain it.

Please follow this tutorial and post an MGADiag report - then we can see what the problem is.

Ignore errors produced when clicking on the Copy button - they simply mean that the tool could not create the backup files for some reason. The data is still copied to the clipboard for pasting to your response.

Please also state the Version and Edition of Windows quoted on your COA sticker (if you have one) on the case of your machine (or inside the battery compartment), but do NOT quote the Key on the sticker!

I don't have a COA as this is a built-up system.

Found COA sticker on DVD box. Doesn't have the key on it, that is on a separate sticker inside the box.
The following is on the sticker:

Have done a repair install with the downloaded SP1 file.

That all looks perfectly good to me - everything seems to match what you have, and there's no errors in the report.
WIN PRO 7 ENGLISH MEA DVD
The MEA stands for Middle East and Africa - so I know of no reason why MS should think it's not valid, especially as the machine passed validation on the 27th Oct.

The 643 error is notoriously difficult to isolate and fix - and we often have to resort to a repair install.
You say that you've already done one? How long ago? What was the reason for it?

Perhaps we should check that there's no malware present...

Please download and install Malwarebytes Anti-malware (free version) from http://www.malwarebytes.org/products/malwarebytes_free/ - UNtick 'Enable free trial of MBAM Premium' at the end of the installation - and update it, then run a full scan in your main account, and Quick scans in any other user accounts.

Delete everything it finds

Then download the TDSSKiller from here -
Anti-rootkit utility TDSSKiller - and run it.

Then

Please follow the Windows Update Posting Instructions and post the requested data
If the file is too large (8MB compressed), remove the older CBSPersist cab files until the final file is below the limit - you can always post them separately after zipping them. (the forum doesn't allow the upload of bare CAB files, for a number of reasons)

MBAM found nothing.

CBS log attached.

EDIT: I see that the CBS file was not updated. Is this because TDSSKiller found nothing?

The upload doesn't contain the current CBS.log file
