Ran the complete cmds, however:
e. Run the following command to manually recompile all of the default WMI .mof files and .mfl files
 cd %windir%\system32\wbem for /f %s in ('dir /b *.mof *.mfl') do mofcomp %s
returned "File not found".
I repeated the full process and no change.
Below is a raw copy of latest event viewer, First 5 "Warning" then next entry, scores of "Error".
