Lost authenication code

[Edward Parkinson]

I need to redo my xp pro and apparently have lost the 25
digit authenication - key code. Does anyone know how I
get this?

If Windows XP is still installed use a keyfinder

If Pro is still installed on the machine, use the keyfinder utility:

get the free Aida 32, enterprise edition from
http://www.aida32.hu/aida-download.php?bit=32
which is an excellent general System Info tool, and its Software -
Licenses page will tell you the one used for Windows and ones for
several other items.

Note that if the machine came with XP installed, this will probably give
a key used in producing an original image, then cloned to all machines
they make. So it is not the one for a reinstall. But then the key will
be on a label on the case of the machine
