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)

Just the one error in CheckSUR...
Code:
Unavailable repair files:
 servicing\packages\WUClient-SelfUpdate-Core~31bf3856ad364e35~amd64~en-US~7.6.7600.256.mum
 servicing\packages\WUClient-SelfUpdate-Core~31bf3856ad364e35~amd64~en-US~7.6.7600.256.cat
SFC was clear - and no background errors in the CBS.log, at least.
I'll post a fix for the file errors later.

I've uploaded a file - stlaa.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 stlaa in the same place.
Open this folder - there should be one folders inside it (Packages)

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

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

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

Hi Noel,

I have followed your instruction to download the package and run sfc /scannow, and I attached the CBS.zip file for your perusal.

I tried to manually run windows update from control penal, seems like the 800F0900 still happened. Do I need to restart windows and try to update again?

Thanks.

You only posted the CBS.log file - not the CheckSUR log.
I can't even tell whether you ran the CheckSUR tool after copying the files?

Please post the requested data.

Hi Noel,

Ok. I have recopied the package folder into Windows\temp folder and run sfc /scannow. The CBS log folder only contains 1 log file:CBS log file. I can't find the CBS persist file generated. Please refer to my CBS.zip attachment:

I am not sure what procedure that I have missed.

Thanks.

Regards,
STLai

This is what I'm talking about - CheckSUR rather then SFC/CBS

Please download and save the CheckSUR tool from http://support.microsoft.com/kb/947821
(you'll need to look in the details for Windows 7, downloading from the Microsoft Download Center)

Run it - The tool can take anywhere from 5 mins to a couple of hours to run (or 'Install') depending on how much it has to do, and may exit silently - it may appear to freeze for most of that time, but be patient.
The result is logged in the C:\Windows\Logs\CBS\CheckSUR.log file - and an archive …\checksur.persist.log file

Then zip the CheckSUR.log and upload it to your OneDrive Public folder so I can take a look - post a link in your reply.
