Craig,
If I am not mistaken, he will most likely have to do a clean install to be legit. Which means using the clean command. I will let someone else explain how to do the clean command. Myself, I wouldn't use clean all command because the clean command is faster. If he has more than one hard drive inside his computer, he will have to use the clean command for each drive.
Make sure to backup any data he wants to keep.
