Although there are claims this was fixed by a Microsoft patch, I’m still getting the same unreadable log file after running get-windowsupdatelog. Is there a particular windows update that fixed this that I might be missing?

In reply to Stephen Owen. Thanks for the nudge. I had forgotten about this post.

You should update this post, since it’s now a LOT easier. All yo uhave to do now is run ‘Get-WindowsUpdateLog’ from PowerShell, and it cruches the files into a standard text file.

I got this far…
I had a folder called wulogs with the ETL files… I hunted and found tracefmt.exe finally after installing that pack wdksetup.exe

C:Userszerou_000wulogs>”C:Program Files (x86)Microsoft SDKsWindowsv7.1ABinx64TraceFmt.exe” -o Windowsupdate.log

…Unfortunately my output is unusable.. windowsupdate.log is completely empty …
where are the raw ETL files for windows update stored

tracefmt takes centuries to install. I installed this and hoped in a command prompt with administrator privledges I could run tracefmt.exe command
tracefmt
and it would give a message… showing that the exe exist?
I downloaded this which took forever by the way but no avail..
wdksetup.exe
