I can  change an icon to any quick launch icon by using "Properties- change an icon," but I only get about four choices. How can I select from a larger range of choice. Thanks, billrobb

   You can do that by right clicking on any shortcut or icon (not just icons in Quick Launch) and selecting Properties.
   Most exe files have at least one icon embedded in the exe file.  When you click on the Change Icon button, it shows you the icons embedded in the specified file.  Shortcuts are set up to use the main icon in the exe file that it is linked to by default.  If you want to change this you can.
   There are icons in exe, ico, and dll files (not all dll files have icons).  Shell32.dll in the System32 folder of Windows has many icons in it.
   You could make your own icons using a graphics program, save them to ico files, and use them.
