It's kinda an emergency at my end, so forgive the brashness....

But I've got 3 Dell machines with XP Pro OEM licenses, their OEM keys are on the CoA stickers on the side of the cases.

...but the company's lost their installation discs and they need stuff back online by Monday, so I'm just torrenting an XP Pro OEM ISO as I write this (now is not the time for lectures on the specifics).

Would the OEM keys on the side of the cases work with this ISO? I can't help but think not, because they're Dells, and Dell (was) in bed with Microsoft and stuff.
