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