Yesterday I installed Windows 7 (32 Bit) in a VirtualBox Virtual Machine; but the machine got corrupt; so I reinstall Windows 7 again, today. I could not enter my product key, so I did the "slmgr.vbs /ipk PRODUCT KEY" then "slmgr /ato" (without quotes) and a few moments later a message came up saying that "The activation server determined that the specified product key has been blocked." This is a legal copy of Windows 7 bought at Christmas 2009. (which pisses me off because I did not pirate it.) This is why I love Apple; NO product keys to worry about. (But I need Windows 7 for some Win-Only programs.) I can see a lawsuit arising because of this issue effecting even LEGAL copies.
