I have just recently upgraded my system with a new Mobo and Graphics card. I am still running XP until I can buy 7. When I booted up the computer, it says that I have to activate my Windows product. This is impossible because I'm still using the same HDD and I have owned this copy for about 10 years. i do not have the reactivation codes and when I call the number for activation they say that it "Is not a Windows product". Any help will be nice.
