Microsoft Windows comes with a standard volume control which is a simple and plain tool to control the volume of a Windows system. Increasing or decreasing the volume using this standard control is tricky and not so easy. Fortunately there is a replacement tool called Volume2 (or Volume2) available for Windows volume control. Volume2 is a free tool that sits in the notification area and lets you control the volume using your mouse wheel or pre-specified hotkeys of your keyboard.
Volume2 is a free and open source advanced Windows volume control application. It can completely replace the standard volume control of Windows. This application lets you easily change the sound volume just by rotating the mouse wheel or by using keyboard hot keys or just moving your mouse near a screen edge. It includes an audio mixer with advanced volume controls support, a scheduler and an on-screen display (OSD) with skin support. It also gives command line support and the ability to store and recall different unlimited presets via one mouse click or system-wide hot keys. It is a multilingual application that supports many languages.
You can download either the installable edition of Volume2 or the portable edition. I prefer the portable edition as it does not require to be installed on your system. When you run Volume2, it places an icon in your system tray (notification area) at the bottom-right corner of your screen. You can double click on this notification area icon to open the Volume2 options window.
