Hello, I am helping a friend that had a motherboard go bad on an eMachine. I installed a new motherboard and everything works fine. When I try to reactivate the Windows XP home it tells me , It does not recoginize the number as a valid product ID. I know it has to be a valid number because he bought it new at Best Buy. I am told by Microsoft that I need to contact eMachine because they owned the copy of Windows that went with the computer. Does anyone know a way around this? I need to save the information on the hard drive and don't want to erase it and start over. I read somewhere if you get the same chipset it will not require the reactivation, but that did not happen in my case.
Thanks for any help you can give.
