It's not quite as simple as that for XP Home. There is XP Home OEM (the kind you'd get from New Egg) and then there's XP Home OEM huge-pc-manufacturer-version (check it out even the product keys on said computers have the manufacturer's name - HP, Sony, etc). Your HP/Sony/Toshiba Home product key won't work with regular Home OEM; this is also true for XP MCE 2005 but not for XP Pro. My work laptop has XP Pro and I was able to use a generic OEM disc to reinstall Windows using the product key on the laptop.

This doesn't work with Home or MCE. My guess is that the huge OEMs get a special version of Home and MCE because they ship so many of them; while they just use or modify regular versions of Pro OEM. The best course of action would be to try to find someone who has an HP/Sony/Toshiba OEM OS install disc (not a restore disc) and make a copy of it. A buddy of mine bought an HP laptop and it came with an MCE 2005 install disc in addition to the restore disc; I quickly "borrowed" it from him and I have been able to use it to reinstall MCE 2005 on HPs and Sonys (haven't tried on anything else) using the product key on the computer.

Interesting, I haven't had any success; it would refuse to take the serial number. Same with MCE 2005 OEM.
