I got a copy of xp but when I go to install it I need to type in a code for authentication. the code was on the box, but it was lost some how so, unless I can get it off my computer.... I dont know what els to do . any help would be cool.
If your computer still boots into it's old install of windows XP, you can run a little program called magic jellybean Keyfinder which will find your XP installation key. I suggest you write it down, preferably on the XP CD itself.
