It should work since I used Nvidia 15.25 (Vista) before they released Windows 7 drivers. Could be a problem on the network part thou, since the registry differs slightly. Shame that I don't have a Vista installed, else I could test it out for you. How much space are you using on the Windows partition? Reason I ask is because lately I started to use COMODO Backup (FREE), so I can do crazy things to my Windows and restore if hell breaks loose (which happens sometimes) My used space is around 19GB, takes 5 minutes to backup and 8 to restore.
