How to format windows 7 ultimate without removing the windows itself?
 

Hi i tried installing windows 7 activation key but i cant find Windows 7 Starter Product Key my serial and every time i boot up the Office 2007 Pro computer it goes straight to the setup Office 2007 Professional screen. I have a Office Pro Plus 2010 Key with a serial and i want to install it but Office 2010 Activation how can i get to the setup of windows 7?

Does changing Windows XP for Windows 7 affect the information fund on my computer?
 

I am using windows 7 64bit and my windows 7 32 bit is activated. Since i have installed Office Enterprise 2007 i have never enabled Office 2007 Enterprise Key as i am unsure that it may deactivate my Office 2010 Activation Key or may hamper working of my non genuine windows. So i want to know if it will be safe to enable Office Professional Plus?
