SBrehler,
Whether your customer still qualifies to use the license for XP that was put on her laptop by the school all depends upon the agreement the school has with Microsoft.
Some schools have made arrangements where their student software agreement allows the students to continue to use Microsoft software even after the student ends their association with the school (graduates/transfers/drops out/ etc), and some school agreements are good only so long as the student is an active member of the school's student body. The tech folks at the school are in the best position to answer that question for you.
If the student is still allowed to use the software, then the tech support staff at the school should be able to supply a disc for reinstallation/clean installation. If still allowed but no CD is available, then I would expect that any genuine Volume Licensing CD for the software in question (XP Pro) plus the still-valid VLK currently being used by the school should get the job done.
If student is no longer allowed to use the installed XP, then the XP license that came with the laptop (as evidenced by the CoA) is still 100% legitimate and authorized, so then it's just a matter of getting the Recovery or OS Reinstallation CDs or Reovery Solution that was provided by the laptop manufactuer and applying it, after of course offloading any data that student needs.
