Opera is an internet software suite which handles internet based tasks like sending and receiving e-mails, display of websites, chatting, downloading and reading web feeds etc. Users need the option to restore web settings back to the default settings after making any changes. No option is provided in Opera settings to restore the default settings in Windows Vista/7. In order to reset to default settings you have to close the Opera browser and locate the settings file Operapref.ini and delete it. Restart your Opera browser and the file will be rebuilt and Opera is restored to its default settings.
