Question about loading XP home OS

[Cort]

I have a computer which had XP professional loaded, but
this machine got so corrupted with internet garbage that
I wanted to wipe it clean and install a new OS. (I ddn't
have the key for the professional, so I bought XP home
and installed it using the installation wizard). Now I
have BOTH OS on the computer! How can I wipe out
everything associated with XP professional?
