I do not condone this. I bought and paid for two versions of WinXP Home and have them installed on our two XP Home systems. 100% Legit.
That being said, a lot of you have pirated copies. And because your are “pirates”, a lot of you cannot install the critical SERVICE PACK 1. These instructions from a knowledgeable yet anonymous source should go a long way in helping you.
Best of luck!
UPDATE 7/18/2006 – If you are trying to find the Product Key from your Windows XP CD, here’s some info that might help.
If you’re having trouble accessing the site in the link above, be patient. Make a note of it and try again down the road. I think the site is run off a guy’s personal computer/server and it may not always be available. Sorry.
Update: The tutorial has been moved here. I suspect it will move again one day.
