I would like to Know is it safe for me to use windows xp because my stepfather bought him a computer and it came with a windows xp disc and he used it for his computer but I would like to know is it safe for me to use it because my mother has windows 98. So I just want to know can I use the windows xp disc for my mother computer. I mean even though my stepfather used the disc for his computer could I still use it for my mother computer so I could upgrade it. Thanks
