Good to see them encouraging piracy by making people who pay for it jump through the hoops. "Look at me! Look at me! I paid for this!" While the pirate simply uses an activation crack and goes on their way. Yes, illegal, but who cares? How many people have actually read a EULA? I tried to a few times, made no sense to me.
they made little sense to me as well but I think we all know what the intent is
My question assumes the drive is blank(you wiped the disk for example) in the same computer as windows 7 upgrade had been used to upgrade another windows and activated successfully in the past. If it clean installs using the windows 7 upgrade disk, entering no liscense at time of installation. Can it then be activated because it had already been activated in the past? No different computer or hardware.
When you activate your OS (not your hardware) it generates a Globally Unique ID. If you dont change the hardware at all it will stay the same. MS gives you abt 5 re-activations (at least in vista they did) before you will have to call them with your Key and dvd to get a manual key..
Realize that any difference (HD, ram, cpu, bios upgrade, etc will then generate a different GUID and count towards the ~5 re-activations over the internet.
With a retail purchase I believe you were allowed to install it as many times as you like on one computer. Also, the question may have been answered, I'm just trying to clarify exactly what i meant, though I doubt it's too clear.
