Hi,
Usually it happens because this folder is missing:
C:\Users\<user>\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch
Next time you reboot, check to see if it is there. If not, recreate it
(file/new/folder) before you re-enable the quicklaunch in taskbar
properties. That should resolve it.
The above folder path is a hidden, system path, you may need to adjust your
folder options/view tab in order to see it.
