Hello all. This may sound like a bit of a stupid question, but seeing as I don't know the answer, I thought best to ask. I have on one pc an OEM copy of Win7 32bit. This rig has 3gb ram and a 1gb GPU installed. Obviously due to the limitations of the 32 bit OS, some of the Ram isn't being used. My question is this. I am going to be buying a retail copy of Win7, for use with a new build, using the 64 bit disc. If I were to do a fresh install on the old pc containing the 32 bit OS, would the existing licence that is on the machine still be valid? The new license would be attached to the new machine. Thanks in advance to those who answer.
