How do I put windows 7 and xp both on my laptop?
 

Ok, so I upgraded Office Pro Plus 2007 Serial Windows Vista Home Premium to Office 2007 Professional Plus Activation and I was wondering whether I could Office 2007 Ultimate Activation Key from Windows 7 to Windows Vista? Windows 7 makes the Microsoft Office 2007 Enterprise Activation Key horribly blur, is not Office 2007 Pro Keygen with tons of programs and I am not used to it. I can't play my game and I really want to change back as soon as possible. Can anyone help me? Also, I can reinstall everything if needed, but I don't know how to. Please help!
