Source position: eventlog.pp line 81

`public function TEventLog.UnRegisterMessageFile: Boolean; virtual;`

## Description

UnRegisterMessageFile can be used to unregister a message file previously registered with TEventLog.RegisterMessageFile. This function is usable only on windows, it has no effect on other platforms. Note that windows locks the registered message file while viewing messages, so unregistering helps to avoid file locks while event viewer is open.
