If your Windows 8 has started misbehaving it can be difficult to know where to start looking. One of the first places the experts go to is the log files maintained by Windows, which record unusual or abnormal activity and error messages.
The logs can be opened in the Event Viewer and quite often the information stored there can help you to identify the source of the trouble. It’s worth a look in any case as you may spot a potential problem that until now Windows has managed to fix on its own. The easiest way to open the Event Viewer is to type ‘eventvwr.msc’ (without the quotes) in Run on the Start menu; double click the Applications and System logs and look out for any red ‘X’ Error entries.
