Quick Launch in Windows 7
Right-click on the taskbar and then click on Lock the taskbar to uncheck (unlock) it.
Then click on Toolbars and then on New Tool Bar in the menu that pops up.
Copy the following
%userprofile%\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch
Paste the above into the Folder: dialog box near the bottom of the Toolbar - Choose a folder window and then click on the Select Folder button.
You can get rid of the 'Quick Launch' text by clicking on Show Title to uncheck it.
For those who don't want to read down through all the many comments, there is a solution to the problem with the Quick Launch disappearing on re-starting your system. If you have the language bar on your task bar, there is a conflict and the Quick Launch suffers for it. Moving the Language Bar off of the Task Bar solves the problem.
Thanks for reading and I will be updating this page again once I've had a chance to use the final release of Windows 7.
