However, what more interesting to me is the results of a coupe of earlier scans you did...

The first on Jan 7 gave this Summary (the one on Jan 8 was simply a cleaned-up run of the same system)

The second, on April 30 gave this... (and the latest scan is a cleaned-up version of this one)

Code:

Since all runs were done using the same version of CheckSUR, this means that something is repeatedly corrupting installs through Windows Updates.

I'll post a fix protocol later.

I've uploaded a file - jsmaa.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 jsmaa in the same place.
Open this folder - there should be one folder inside it (Manifests, )

Copy the content of the manifests folder (.manifest files) into this folder:

C:\Windows\Temp\CheckSur\Winsxs\Manifests

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

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

The run an SFC /SCANNOW, and post the new CBS.log file, and we'll see what else needs fixing (if anything)

Here's the CheckSUR log summary...

Summary:
Seconds executed: 1339
Found 54 errors
Fixed 54 errors
CSI Manifest All Zeros Total count: 28
Fixed: CSI Manifest All Zeros. Total count: 28
CSI F Mark Missing Total count: 26
Fixed: CSI F Mark Missing. Total count: 26

There appear to be no remaining errors, so with any luck, Windows Update should work now.

do a Check for updates, and then attempt to install ONLY the oldest update - what happens? If it installs OK, try the rest.

Please post your C:\Windows\windowsupdate.log file

One surprising thing strikes me immediately - you are still using a very old Windows Update Agent version.

It would be a good idea to update to the latest version - http://download.windowsupdate.com/wi...nt-7.6-x64.exe

( I have no idea why it hasn't already installed - it should have done so more than a year ago!)
