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