, not the WU logTom - that's the detailed CheckSUR log you pointed to, not the WU log
The WIndows Update log is at
C:\Windows\WindowsUpdate.log
I never knew quite what to call it when I asked for it, but it contains information about problematic Windows Updates, so I thought that the Windows Update log would do. Sounds more user friendly than a CheckSUR log 
You don't get a CheckSUR log unless you run the tool - which the OP doesn't appear to have done yet.
My mistake. Thanks for your help Noel
