when i got my Dell computer, I had windows vista ultimate installed on it.  As you kno it comes shipped already installed with a disc for re-installation purposes.  They sent me the 32 bit version of vista ulimate and i want to change to the 64 bit so that i can use my computer to its full potential.  But all i have is the 32 bit version.  Vista ultimate is supose to come with both the 32 bit and 64 bit options, right?  My warranty is expired and i cant even send dell a email without getting charged money.  Is there any why for me to get the 64 bit version without having to go out to a store like best buy and just buy it? Cant Dell send me a installation disc for the 64 bit version for alot cheaper?  Commets, answers, solutions appreicated.  Thanks.
