The mouse should have this functionality activated through its application. If you have the software installed, go to System Tray and locate the application for the mouse. Double click it to open its options and you will have the possibility to configure it from that location. Alternatively, go to Control Panel > Mouse or Control panel > Hardware and sound > Devices and Printers. Locate the mouse, right click it and select Mouse Settings. If there are options available, you will have the possibility to configure it from that location as well.
