I am reinstalling Windows Vista on a friends Compaq computer that came with Vista and the key on the COA stricker doesn't work (of course). Usually I call Microsoft activation hot-line and they give me a new key. I am trying to find a faster way to legally activate when Vista. Is there a disc I could download that would automatically find the key and install it. How does Geeksquad and the other PC repair shops reinstall Windows. Thanks for your Help guys.
