So i bought a computer nearly a year ago, it came with Windows 7 32 bit installed, a disk for 64 bit windows and a sheet of paper with a Code for windows to be genuine. I used the code with the 32 bit windows installed thinking i wouldnt ever need to installed the 64 bit version... Well... I kind of want to in the case i want to install more than 4 gigs of ram.... my question is would it be no longer be a genuine copy of windows if i were to install the 64 bit version since i used the code on the 32 bit version or would it somehow know it still the same computer...Probably a dumb question but i'd appreciate any answers
