I confess I don’t much like it, preferring the “Computer” icon instead.
You can easily change it by getting the “Computer” icon from here:
C:\Windows\System32\imageres.dll
Note, that in order to change the default icon in the taskbar, unpin explorer from the taskbar, change it in the the Start Menu, then repin it to the taskbar.
For setting up the quickstart menu, Directions for that are here: http://www.essjae.com/computers/computers.htm
