Attempting to start the Windows Event Log service manually via the Services MMC resulted in error 4201. The error message is provided below:

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.

And the following errors popped up when opening the Event Viewer and Task Scheduler.

Event Log service is unavailable. Verify that the service is running.

Task Scheduler service is not available. Task Scheduler will attempt to reconnect to it.

The problem turned out to be the incorrect permissions for the C:\Windows\System32\LogFiles\WMI\RtBackup directory. The SYSTEM group needs full control permissions for the directory only when the Windows Event Log service would start.
