I am using Windows XP, Office 2003, and some other software in my computer now,
If I install Windows Vista, will it take away my Office 2003 and all other softwares? and I need to install Office 2007?
My saved files and documents, will it be erase too?

Thank you so much, Please Help!!!

if you upgrade from windows xp to vista, that will not take away all your application in your computer. If you install a new vista, means you format the harddrive and install the OS, then you need to reisntall all application.
