how to safe xp product activation key (WPA)?

[my2001]

Searched on the forum and the net but unfortunately couldn't find helpful information, so I'll try it here:

I install my XP Pro silently and activate it afterwards manually over the internet. Okay so far.

But how can I keep the activation key for the next unattended installations on that same system, i.e. to get rid of activating XP again and again?

What I found out is that just saving and copying back of wta.* like almost everybody suggests doesn't seem to help?!

Save the following file and replace it during your unattended install:

c:\windows\system32\wpa.dbl
