I just recently had my pc fixed and it had to be formatted. My windows CD key wont work do it being used to many times. I’m the only one that uses the CD key and iv used it 5 or 6 times to format my pc. I have a few games as well that wont install do to the same problem. Mass Effect, F.E.A.R. 1 and 2, the orange box and dawn of war 2. Id like to know how I can get them key codes back so they can be use agene as a fresh restart to my PC.
