The very last sentence in ME255629 mentions:
"IF the previous steps do not work then delete all files in the %systemroot%\SYSTEM32\WBEM\Repository folder and restart the computer or server."
I only follwed this advice from the article and it worked.

In my %systemroot%\SYSTEM32\WBEM\Repository I only had two files:
$WinMgmt.CFG
CIM.REP
After moving the files and restarting both Windows Management Instrument services the event never reappeared when the machine was left on for sometime. I rebooted eventually to make sure the event didn't come back and it didn't. In %systemroot%\SYSTEM32\WBEM\Repository I now have 3 files:
$WinMgmt.CFG
CIM.REC
CIM.REP
Don't forget to delete the original files you moved.
This could be due to insufficient security access to the "<%SystemRoot%>\System32\WBEM\Repository", insufficient disk space or insufficient memory.
