|On a factory cd or a burned copy of a factory cd the is no key.|
What there is , is a program that excepts a given number of keys based on the version of the cd. Is it a Dell a Gateway HP? and if so what sp is on it and what version is the cd.
Is it retail, OEM...?
Finding a key just to install is easy......IE installing using a Dell cd on a HP machine.
But you will need to activate and the key you used to install most likely has been used before, so you end up with activation problems.
I use the same key over and over on a slip streamed version of xp.....but after installing I use Microsofts key updater and the COA on the machine to make it a legal copy.
So you need three things.
A working key for the type of cd
Microsofts key updater (it is free)
A COA sticker to update the key
