This CD-key works only on clean installed Win7. If you purchase this version, you will need to re-install your Windows 7.
I have done a few Windows re-installs and upgrades and this was the simplest. I upgraded from Windows Vista Ultimate to Windows 7 Ultimate. I used the Microsoft Windows upgrade advisor and dealt with the few suggestions advised, downloading any updated drivers for printer and scanner and software. The upgrade install then managed to retain all my programs and hardware with no problems encountered. I had problems with Vista on occassion, which would appear to have disappeared with the installation of Windows 7 and I am very satisfied with the whole process of upgrading.
