Hi,
I'm not clear on the question. But if you are asking can you run Office
2007 using Windows XP the answer is Yes, and it runs faster than under Vista,
at least on my machines.
If you are asking can you run Office 2003 under VISTA the answer is yes again.
If you are asking do you get Excel (Office) with Vista, just as Bernard said
- No.
Excel will probably be supported for some time to come, and even though
Windows XP will officially no longer be supported in the future (I'm not sure
when), you can certainly continue to use it.
