Windows 7 fresh install - 800B0100 update error

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)

Here's the summary from your CheckSUR scan.

Code:

I'll post a fix protocol later.

I've uploaded a file - ra8aa.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 ra8aa in the same place.
Open this folder - there should be one folder 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.

CheckSUR is now happy.

Please go to Windows Update, and run a Check for Updates - what happens now?
Attempt to install ONLY the oldest found update- what happens there?
