I just bought a desktop with Windows 7. During the initial first time setup I entered the activation key with the dashes and clicked the whatever (Next/Continue/Finish) button. Then I realized there was a message below the input boxes indicating that dashes would be automatically inserted. Will the OS parse and disregard my blunder or am I screwed? Can I somehow re-enter the key correctly if there's a prob?
