I replaced the hard drive on my Dell PC. I installed Windows 7 which was an upgrade to Windows XP Professional. When I tried to activate MS said no. For years this was done by using the original OS disk or entering the product code from the original. Is there a way I can activate without reinstalling XP or buying a new version of Windows 7?
