Ok, so I upgraded from 
Windows 7 Enterprise to 
Windows 7 Starter and I was wondering 
Office 2007 Professional whether I could change back from 
Office 2007 Professional Key to Windows Vista? 
Office Professional Plus 2010 makes the screen horribly blur, is not compatible 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 Microsoft 
Office 2010 Professional Plus anyone help me? Also, I can reinstall everything if needed, but I don't know how to. Please help!
