For the most part it seems that Vista drivers work with Windows 7-so will this not work in all cases? I've used Vista drivers several times so far, successfully.
I read that Windows 7 was modified from Windows Vista. Maybe that is why some Vista drivers would work with Windows 7. My experience was that most vista drivers wouldn't work with windows 7. I had to download and install a new driver for my HP printer for it to work on windows 7.
