Is it possible to extract WINXP key from Nlite customized windows?

[synthro]

The thing is this, i had a valid Windows XP cd & key that i used to make a customized Nlite installation CD.

However, now i am in the situation to have lost the old valid XP cd & key with it, and want to install windows 100% original again.

So is there a way to extract the product key from the Nlite Windows CD? That would be of great help to me.

Sorry for any bad english.

Look in i386\winnt.sif or \LAST SESSION_U.INI.

Great!

Second question. This key im using came from an old Windows XP Professional CD without any service packs.

Is it possible to use this valid key with a new service packed Win XP cd? Or does it have to be exactly that version of windows (non serviced..)

It can be any service packed version.
