X-Mouse Button Control – Advanced customization of your mouse buttons

A multifunction mouse usually has at least 6 buttons (left + right + middle buttons, DPI button, and two side buttons), and their functions are usually unchangeable, except for those high-end mice with programmable buttons whose functions can be set after installing the official driver. If you want to set any button of any brand of multifunction mouse on demand, then X-Mouse Button Control is what you need.
