7+ Taskbar Tweaker is a small tool you can use to tweak the Windows 7 taskbar behavior. Among other things, you can define how applications are grouped, customize left click actions, disable thumbnail previews, set a double-click action for empty space on the taskbar (e.g. Show desktop) and force the combining of grouped items. The program also includes a Taskbar Inspector, a small tool that lets you manage all your current taskbar items.Please note: Due to it's behavior, some anti-virus programs will alert you of a potential threat!
