    Hi, I need to reinstall XP Home SP3 on a PC, but sadly I only found Retail ISO's out there, so I would like to know if it was possible to convert it to OEM.
    I don't wanna make an OEM SLP ISO with bios files and everything, just a normal OEM ISO.
    So if it's possible what file do I have to change?

    Thanks.

    You just need to edit 1 file for that:
    i386\SETUPP.INI

    Open it, and you'll see something like this:

    Code:
    [Pid]
    ExtraData=786F687170637175716954806365EF
    Pid=76477000
    
    Edit the Pid data, so that the last 3 digits read "OEM". Like this:

    Code:
    [Pid]
    ExtraData=786F687170637175716954806365EF
    Pid=76477OEM
    
    This example is from XP Home English, which has a Product Code of 76477.
    If your XP CD is in another language, then you'll have a different Product Code (don't worry, that's perfectly normal ;) ).

    If you want, you can also change the volume label to reflect the fact that the CD is now OEM.
    For example: GRTMHFPP_EN would become GRTMHOEM_EN.
    Of course, this is entirely optional.
