legal) .... depending on what he has (on the hard drive (both in a

on drive C

, on any restore media that came with the computer, and even
JUST using the product key from the COA label (with a GENERIC OEM media
that did not originally come with the Sony laptop) .... it may be
possible for him to do a clean "reinstallation" of XP on another
computer, and it may even both work and activate / pass WGA.
The question asked is complex and has a huge number of variables. There
is no easy answer given only the information in the original post.
