Download WizMouseWizMouse allows you to scroll the window under the mouse with your mouse wheel even if the that window doesn't have input focus. Windows 10 already has this functionality built in so WizMouse is most useful if you're using earlier versions of Windows (Windows 2000, XP, Vista, 7, 8). WizMouse is FREE but donations are welcome.
