  My daughter been running Windows 7 Home Premium and the hard drive failed.  A Dell support person came out and installed a new hard drive with Windows 7 Professional. She had not requested the Pro version. The technician provided the product key but when she tries to do the activation it apparently needs a license code or key. She has tried Microsoft and they told her she needs to have the license key. My daughter just had a new baby and has no time for spending hours on the phone. Can anyone please help?    The product key which is on a blue sticker,  the tech gave your daughter, should have worked if it for win 7 pro, but it should say win 7 pro on the blue licence. Alao did the tech give your daughter a reinstall dis for win 7 pro. Other that that she can install win 7 HP from a dell disc, and that will activate on a dell motherboard, also she should have a blue sticker stuck to the system case with a blue sticker on it, whith a number for HP.
