Replaced failed hard drive on Acer Aspire 5734z. Windows validation.
My hard drive failed on an Acer Aspire 5734z that I have. I replaced the hard drive and reloaded Windows 7 Home Premium 64bit from a downloaded copy. Since this is the same OS as originally came on this laptop, how do I get it validated? Or, alternately, how do I get a replacement OS without having to buy it again?
