So you cloned your original disk then copied it to another, which you used on the same computer? Be prepared to call Microsoft; maybe your Windows saw it was on a different drive, and decided that it was cloned.
I was just on an upgrading binge. Yes, I was replacing the hard drives on the machines for more storage. The problem if you can call it that, is that on the "host" machine with the back up software, where I would image the drives, it would watermark my screen, at first reboot, but then would show "genuine" in the Computer>properties screen. I don't think I am doing anything contra to the Window's EULA, I'm not pirating anything, just transfering a disk image, for the same machine it was installed on.
I have finished, my wife and I are just a little tech crazy, we are running 3 desktops, 1 home network server, 2 laptops, and a mac book pro. I have upgraded all the hard drives on every machine, except the mac.
