Win-XP Support

It is my understanding that when Win XP is no linger supported all of the updated go away, even the ones that are currently available..
So is there a way to buy a CD/DVD with Windows XP, SP3, and all of the updates on it.. Or is there a way to build a CD/DVD that contains Win-XP and all of the updates..
I am not very experienced at this so keep it simple….Thanks Bob
