Go to (depends on where Excel is installed, I use Excel 2007 in Windows 7)
C:\Program Files\Microsoft Office\Office12
Create a shortcut to Excel.exe on the desktop and right-click on it and go to properties
Go to the tab shortcut , and then at the bottom of the tab, then click the change icon and confirm your choice of icon by clicking OK.
Drag the Excel shortcut to the taskbar and Da Da, you will get the Excel launch window with a new shortcut.
