Users interested in 3rvx windows 7 64 bit generally download:
3RVX is an application that emulates the on-screen volume control found in Mac OS X. Every Mac comes with a keyboard which has 3 buttons for volume control. When you press volume down, volume up, or mute, it shows an icon on the screen which reflects the button you just pushed. It is quite a good system and 3RVX does just that, but in Windows.
