OK,... I get a lot of PM's about changing the Icons & Commands.
In this post I shall try to explain how to change some parts of the Office 2003 key.
Open Regedit (Start -> Run -> Regedit) and search for the CLSID: {00000000-5070-0000-0000-000000000002}.
(You can find this CLSID in the "Add Office 2003.reg" file)
Now go to the "DefaultIcon" key, you see a line like this: "%ProgramFiles%\Common Files\Microsoft Shared\Office11\MSOicons.exe,6".

You can change this line to point to any icon you want, right click on "(Default)" and select Modify, and change it to the location of your Icon.
If you want to change the Command names (the ones that appear on the context menu), go to the Shell key and expand it.
Find the key that you want to change (in this example Excel).

Cick on the Excel key and you see the line: "&Excel 2003", you can change this to any name that you want.
The & character is for the keyboard shortcut, put it before the letter that you want to use to activate the command.
To change the command select the "Command" key and you see a line like this: "%ProgramFiles%\Microsoft Office\Office11\Excel.exe".

If you use Office XP you can change this to "%ProgramFiles%\Microsoft Office\Office10\Excel.exe".
When you are finished you can export the key: Right click on the key {00000000-5070-0000-0000-000000000002} and select "Export" and you can safe it as a reg file.
I hope this helps you all!
