I have just replaced my motherboard after the original was fried by a lightning strike. I'm thrilled that the computer now is working (I'm not a computer geek so replacing the motherboard successfully was a major triumph for me). However, now I am getting messages that I cannot use Windows update since my Windows 7 does not pass the validation test. I went to the Microsoft site and downloaded software to test the validity of my operating system and (hopefully) reregister it, but was unable to. I have the product key for the software but the Microsoft program doesn't even ask for me to reenter it. How do I re-validate my operating system without having to purchase or reinstall the software?
