It's a pirated copy which was burned at too high of a speed (anything greater than 2X) and is why:
A) He is asking for a key in this thread
B) He is asking why it is giving him a missing files (syntax 1386\asms) error in another thread.... not to mention when Stephen asked him why he doesn't have the genuine XP sticker on the chassis he is long gone.
If it is in fact a legit copy of XP and I am wrong about this, which I doubt because I have seen this a hundred times, it is caused by a smudged or scratched cd that causes the particular file or files to not be read.
