Windows update repeatedly failing with 3 updates

I've uploaded a file - csbah.zip - to my OneDrive at Noel's OneDrive
Please download and save it.
Right-click on the downloaded file, and select Extract all…
Extract the contained file to your SFCFix location - which will create a SFCFix.txt file there.

Open the SFCFix location in Windows Explorer - and drag the SFCFix.txt file over onto the SFCFix.exe file - this should force SFCFix to run the file
It will create a new log file - please upload that.

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

Post the new CheckSUR.log

With luck and a following wind, that'll give us a clear CheckSUR!

Phew!

Now we need to run another SFC /SCANNOW and have a look at the results in the CBS.log file

The SFC scan is now clear - and there are no errors in the background CBS data.

Do a Check for Updates, and install only the oldest update found - then reboot, and install the rest (assuming all goes well)

Good Luck!

This one is an important update.
Try installing it from the standalone here - Download Cumulative Security Update for Internet Explorer 9 in Windows 7 x64 Edition (KB2957689) from Official Microsoft Download Center - if it fails, post the C:\Windows\Windowsupdate.log file and the CBS.log file and I'll see if there's any clues there.

Did KB2963950 install properly?
If so, then KB2957689 is not required - they are effectively the same update tweaked to allow for alternate starting-points.
