I've uploaded a file - tzyaa.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 tzyaa 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.

Thanks for the quick reply, here you go.

CheckSUR is happy now

Do a new Check for updates, and attempt to install ONLY the oldest update found.

If it fails, upload the C:\Windows\windowsupdate.log file
If it succeeds, try installing the remaining updates.

Thanks - both updates installed successfully, and no problems after restart. Is there a reason this error occurred, as I haven't seen this come up before?

 

[NoelDP]

Sometimes stuff like this 'just happens' - with a single error such as this it may have been a momentary power fluctuation causing a mis-read/write to either memory or disk.

I see - thanks for your help again, I really appreciate it.
