IE 11 fails to update with KB2909921

I'm running Win7 64 SP1 on a 'standard' workstation setup. KB2909921 (cumulative security update for IE11 for wins for x64 based systems) fails to update. It succeeds on the first install pass then reverts the changes about 80% into the post reboot pass, then restarts the computer. The resulting error is 80073AA2.
All windows updates other than KB2909921 update perfectly.

I've worked on this pretty hard. I ran all the Microsoft fixits, the SUR and SFC tools, deleted the contents of the \software distribution\Data Store folders as directed on technet, reset windows update and deleted the update history.

I then did a very thorough scrub of the machine with the guys at the Malwarebytes help forum - three days worth of scrubbing - and came up mostly clean - a few tracking cookies, etc. They're quite sure I'm virus and malware free.

Then I redid all of the microsoft fixits, tools, resets and folder cleanouts as directed, and the update still reverts on reboot. All of the other recent updates work fine, though none are 'cumulative security' updates.

SFC runs with no errors -100% file integrity.
SURTool also shows no errors, zipped log attached.

So then I read the Windows update.log and the CBS.log carefully and noticed that I was getting errors like

Failed to get session package state for package: Package_3_for_KB2872339.......[HRESULT = 0x80070490 - ERROR_NOT_FOUND]

Leading to three errors of the form
2014-02-28 19:59:36, Error CSI 00000003 (F) Logged @2014/3/1:00:59:36.306 :
[ml:170{85},l:168{84}]"WmiCmiPlugin wevtcfg.cpp(2258): InstrumentationManifestAssert failed. HR=0x80073aa2."

I checked out the web on these error and found no really straight answers.

The offending updates leading to the 80070490 errors are
Update Installed type
KB2872339 9/12/2013 security
KB2904266 12/11/2013 windows
KB2563227 08/14/2011 windows
KB2839894 06/13/2013 security
KB2560656 08/14/2011 security
and I think this list is complete.

Now I saw a couple of posts where problems of this nature were cured by uninstalling the offending updates. I could try this - I can see clearly where they are in my control panel/programs and features/installed updates, and I could easily try uninstalling them and just see what happens.

But some of these updates have been on the machine since August 2011, so I fear that uprooting them may get the auto-updater even more tightly wrapped around its axle than it is.
I thought I would seek some wisdom here before I proceeded.

I could just try a restore in place, but then I wouldn't learn anything, and even this might not work.
Can anyone help out here???

You have errors in the first log that I've never even heard of, let alone seen!
The second is OK.
However - that's not what we need to see.

Please follow the Windows Update Posting Instructions and post all the requested data

OK -

1. Ran SURT - no errors
2. Ran SFC - no errors
3. Ran Win Update on KB2909921 - note that when changes revert you don't get the errors shown on the front page dialog - you have to go back in to history and right click on the failed item and look at details - here we get one error code = 80073AA2.
4. Copied and zipped the CBS.log immediately after running SURT and SFC - attached.

Hope you see something interesting!

Running windows defender and MalwareBytes file system protection and website blocking.

Problem persists with these shut down.

Sorry for the bump on this post, but I was kind of wondering - do I have an impossible problem here?

Thx Noel -

I attach the CheckSUR and Persist logs. These look clean too.

Yet the problem persists - I can't update IE 11 with the cumulative security update KB2909921, nor can I remove the IE 11 update and go back to IE 10. The system consistently 'reverts changes' upon reboot.

I ran a fresh failed IE 11 update attempt, copied the log immediately - it's attached.
