When I first thought of this, I felt like I was a genius, but then I stumbled upon a number of similiar apps. Still, I decided to share this one because it fixes a little compatability problem the other apps had with Vista and Win7.
This app couldn’t be simpler. It’s two lines of code, and all you need to do is scroll your mousewheel up or down while holding down the Win key (the one with the Windows logo on it) to adjust the volume.
