How do you upgrade to 64 bit from 32 bit.
As I am getting conflicting information, Microsoft says you can't upgrade from 32 bit to 64 and having just bought Vista home premium I have to now go and buy a full 64 bit retail.
Don't ask for help from Microsoft as I found them very rude and unhelpful.
Having orderd what I thought was 64 bit upgrade from there site I now have 6 discs mostly service pack one (which is pre-installed on my OS) and no 64.
