7 Taskbar Tweaker is a free application for Windows 7 that lets you change settings of that taskbar without having to deal with difficult lines and menus.
Change the actions associated to right-click and click-wheel, windows groups, drag&drop behaviour, enable and disable window preview,... Make it suit your needs.
All these options are located in the same window, that means it's easy to tweak. Tweak the new taskbar fast and efficiently.
7 Taskbar Tweaker includes an option to be run on Windows startup and manage the changes we have made.
