I was given an old DELL 1050 Inspiron laptop and I didn't have the original XP SP2 CD that came with it and so I just installed with a copy of XP that I had in the house. During install I tried to put in the CD key on the sticker that is on the bottom of the laptop but it wouldn't accept it and so I continued the install using my XP cd key on the install I had. So, now I am installed and updated to SP3 but I am still unable to use the Windows Product Key update tool to change the CD key of the system.
WHy am I not able to do this. Is there a way to figure out why the CD key on the bottom of the laptop wouldn't work? Am I missing something?
