Hi. Most of my friends 
Windows 7 Pro have laptops with 
windows 7 64 bit. They say its great and that it is much faster than Office 2007 and 
Office 2007 Enterprise. I would like to change from 
Office 2007 Professional Plus Key to 
Microsoft Office Pro Plus. Does the chang affect the information and the 
Office 2010 Professional Plus programs found in the computer? I nee your help please!!
