I have an old windows 98 operating system cd that originally came packaged with my old Gateway 2000 computer. There is no cd key so does that mean if I wanted to, I could use this same cd to put windows 98 on another computer(a newly built one for example)? I still have my Gateway 2000 by the way. Was this cd built to work ONLY for that Gateway 2000 or can it be used for other computers?
