Enter in the following folder location and then click Select Folder:
%AppData%\Microsoft\Internet Explorer\Quick Launch
The quick launch toolbar will now be displayed but you will need to move it to the correct location on the taskbar. Just click on the Quick Launch label and drag it all the way to the left.
After you adjusted the width of the quick launch bar the last step is to remove the Quick Launch label. Right click on the text and click on Show Title to remove the option.
You have now restored the classic Windows Quick Launch toolbar.
