hi everyone. I want to upgrade from vista home premium 32 bit to vista home premium 64 bit. i've searched the internet and microsofts website but I can't get easy instructions on how to do this. I don't understand the instructions on microsofts website at all and I don't know a lot about computers. my computer came with 32 bit home premium vista built in. can anyone give me easy instructions for upgrading to 64 bit and what I need to buy.
