I've primarily been a Mac user, but added a PC (HP zBook 15" G2) to my music setup a few years ago. I just purchased a second identical PC to use as a backup machine. My plan is to clone the original PC's drive to the second PC using Macrium. I assume that the easiest way to do this is to remove the SSD from the second PC, connect it to the first PC, clone the first PCs drive directly to the SSD, and reinstall the SSD back into the second PC. Is this Correct? However, I then have to install a different Win 10 Pro key on this second machine and am not exactly clear how this works. Can I use this full retail version from Amazon for the second key? Do I somehow use the supplied USB drive to do this? If so, how? Any help would be much appreciated.
