How to install windows 7 before finishing the installation of windows xp?
 

I have Office 2007 Keygen Home Premium on my Microsoft Office Ultimate 2007 Activation right now. It was pre-loaded Office 2007 Ultimate Serial Key the machine. I'd like to upgrade it to Windows 7. I am also planning on buying a Mac. Will I be able to load the Windows 7 upgrade version on that also? Thanks in advance for your help.

How do I change back from Windows 7 to Windows Vista?
