I upgraded from Vista Home to the Student Edition 32. Unfortunately I did not know the computer would run slower cause of the programs and files brought over from Vista. So now I want to run a clean install of Windows 7 from the download off of Digital River I believe. The only program I really need to backup is Microsoft Office. I do not have the CD anymore, so I need to back it up someway in order to install it again after the clean install. Does anyone know how to do this?
