Ok, so I upgraded from Windows 7 X86 Windows Vista Home Premium to Windows 7 and I Office Professional Plus was wondering whether I could change back from Windows 7 to Windows Vista? Windows 7 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. Office 2007 Keygen Can anyone help me? Also, I can reinstall everything Windows 7 Key if needed, but I don't know how to. Microsoft Office Professional Plus 2010 Please help!
