I have had this problem for a while now, I had a friend of mine re-install Windows XP Pro on my desktop computer. Ever since then it has given me the Purchase a Genuine Windows License. Now, that I am back in school, I am a part of the MSDN Alliance website where I can get free Microsoft products, mostly limited, but Windows XP Pro is on there. Getting to it, my Question, is there a way to install/insert/replace the new product key on Windows XP Pro without me having to boot off the cd to do it??

This is microsofts key changer.

Magic jelly bean is also another key changer, but I think it's a reverse engineered version of mS's.

I load a lot of computers using a vlc cd and then change the key using Microsofts key changer. 95% are excepted by microsoft and the system validated.

Hope this helps.

If in school...do they offer the student version of xp? It is a full version and is preactivated....lol

vlc should be vlk....but I can't spell

Wait for other suggestions, because I can't confirm the one I am pointing you to works.

It has a method that corrupts the current Product Key, which de-activates the system. Then you go to Microsoft and re-activate the system with your valid Product Key.

It sounds pretty good to me, but I suggest backing up first, if you try it.

(edit) Oops, I'm too slow (as usual). :-)

Hi I have my install disk that I bought on line ( xp pro sp2.) I have my Key code but my disk wont read. Is there anyway at all to enter my key code to the copy of windows xp pro sp2 that I now have installed on my computer now? I have a 150GB hard drive and way too much stuff to loose or transfer. I dont want to have to reformat and start all over. Please there has to be a way. Kimberly

I have the steps to change a legitimate key that's stopped working. If anyone wants them, email me.
