Hello everybody!
I have decided to go from windows 7 home premium 32bit to 64bit using my OEM key which should work. But I need a bit of help, I am still preparing for it (backing everything up) but when I am finished what do I do? From what I have gathered I download 64 bit from digital river burn the ISO to a disc put the disc in restart the pc and just follow instructions? I heard something about clicking format drive. Is it better to wipe disc before installation or will windows do it automatically?
Any help will be greatly appreciated.
Thanks in advance.
