I know that this is possible, but I want to know if it is legal. I am building systems for a Microsoft OEM who buys OEM license packs of XP Pro. I do not want to individually install each one, but rather use volume license media to install it unattended, but place an OEM sticker on the side. There is a way to do this using sysprep and then changing the key, but Dell systems are installed using the same key for Pro and another key for Home - on all systems, but stick an OEM sticker on the machine with a different key. So can I legally install XP Corp on all the systems as long as I place a different OEM sticker on the side of each. In this way, each will have a valid license.
