Windows 7 doesn”t have a quicklaunch by default. Luckily, there is a fix. To enable it, add toolbar, other toolbar and include this as location: 

%userprofile%\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch

That site also states you have to save your theme, so do that, to be safe. Just do desktop right mouse, adjust to preference, rightmouse on unsaved theme, etc.
