Thanks guys that answers a lot of my questions.
One question I did think of is about drivers
for things such as printers and scanners.
My printer I do not have to worry about since in updates it had the drivers for my old printer.
I have a Cannon N670U flatbed scanner. As far as I know the only drivers that are available from Cannon are the Vista drivers. These worked fine in Win 7 pro 32 bit as long as I ran them in the compatibility mode.
Will these work for Win 7 64 bit?
