Missing Event Viewer

[RoWin7]

My other machine, also a Win7 Ult, has been running slowly, so I ran a chkdsk. Not only was the log not in the Event Viewer, but there is no E.V. When I tried to start it from Services, I got this message:

"Windows could not start the Win. Event Log service on Local Computer.
Error 4201. The instance name passed was not recognized as valid by a WMI sata provider." It looks like it was composed by a bot :-D

Hello
"Windows could not start the Windows Event Log service on Local Computer.
Error 4201. The instance name passed was not recognized as valid by a WMI data provider." is a genuine Windows error. The error code possibly indicates a corrupt repository. Or it could be a folder permissions problem.

See either of these two 'different' answers for suggestions:
