Dont worry this is typical for bundled software afterall correct me if I am wrong but he didnt get an original windows xp disc did he ? Most likely he's got a system recovery cd.
Since the software is tied into that laptop specifically he cant take that cd and install that version of windows XP on say another PC and hence microsoft doesnt care about registration.... Registration really is for Microsofts benefit not ours.
If you're reallt worried check your version of windows here :
