For a few months, I have been unable to load certain particular Windows updates, first one then growing to four: (1) Security Update (KB2839894); (2) Update (KB2859537); (3) Update (KB2647753); and (4) Update (KB2726535).

I've tried all Microsoft repair options I could find listed on the website, including Mr. Fix-It and Windows System Readiness Aug 2013.

It looks like May 24, 2013 was the first one may have occurred, then June 16, 2013, three failed attempts. :banghead:

I've attached a screen shot of the history of recent update attempts.

I tried to add the zipped CBS file, but a "!" appeared, as it is about .50 mb too large. Please advise how I can otherwise send that file.

Your help greatly appreciated.

Hello and welcome to Sysnative :)

We do need you CBS folder, and since it's too big, I recommend you upload it to a free filesharing site such as Dropbox (http://dropbox.com) or Microsoft SkyDrive (live.skydrive.com). Or if you are familiar with another free service, you can use that.

Kind regards,
Stephen
 
Hello GregWil, welcome to Sysnative!

I'm afraid I have some bad news for you. Your COMPONENTS hive is damaged beyond repair and the only way we will fix this is to perform a repair install as the COMPONENTS hive is the backbone of Windows Update.

From your CheckSUR log, it shows you have 19,328 errors:

Code:
Summary:
Seconds executed: 5545
 Found 19328 errors
  CSI Missing Deployment Key Total count: 2140
  CBS MUM Corrupt Total count: 2
  CBS Watchlist Package Missing Total count: 12818
  CBS Watchlist Component Missing Total count: 4368

Error 0x8007490 translates to ERROR_NOT_FOUND so it's quite clear that Windows Update is failing due to the missing registry keys, which is cannot find for obvious reasons.

Code:
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Windows\System32>err 490
# for hex 0x490 / decimal 1168 :
  SERVICE_CLUSRTL_BAD_PATH                                      clusvmsg.h
  ERROR_NOT_FOUND                                               winerror.h
# Element not found.
# 2 matches found for "490"

C:\Windows\System32>

I know this isn't the outcome you were hoping for, but this is really the only way forward from here.
