XP version from cdkey

[modo77]

Is there anyway to find out which version of XP I need from my cdkey. I've got an old laptop I'm about to sell.
So went to reinstall oem home, as I guessed it would be this version. However its saying the key is invalid.

All the sticker says is xp home.
I bought it second hand which is why I don't have the disk which came with it.

Are they not different for OEM, Retail and corp?

if its on a laptop it will be "xp home OEM" , different key to the retail

That's what I thought, but its saying invalid key

Hmm, I'll try contacting sony then. Cheers
