I want to simply know how much windows 7 will cost, if it is the 64 bit version, at full price. I haven't seen a windows 7 software package that screams "THIS IS THE 64 BIT VERSION!"....so I don't exactly know which one to buy. So i just want windows 7 pricing for the 64 bit version. If it doesn't have a screaming name that include the word 64 bit version in it.. then what would the 64 bit version of windows 7 be called?
Edit: Someone said that both versions are included in my box...although I only have the 32 bit version. It came for free with my computer. I am sure my computer is 64 bit capable and I want to upgrade..what package would I buy?
