 In Windows Vista, Microsoft overhauled the event system.Due to the Event Viewer's routine reporting of minor start-up and processing errors (which do not, in fact, harm or damage the computer), the software is frequently used by technical support scammers to trick the victim into thinking that their computer contains critical errors requiring immediate technical support.An example is the "Administrative Events" field under "Custom Views" which can have over a thousand errors or warnings logged over a month's time.
