One great feature in Linux is its unified place for all of your keyboard shortcuts. You can use it to set them they way you wish. I have used ctrl + down key for lowering the volume and the up key for raising it in my Linux box. However, after switching to windows, you can easily miss that option since there isn’t any option like that in windows. If you want to achieve something like that, you need to install an application called 3RVX (http://matthew.malensek.net/software/). This simple (& smart) software will overtake volume control and provide you with an on-screen display as well. After that, you are able to use win-key + mouse scroll to lower and raise the volume, you can even change those key combinations.
