Microsoft will give you a free license to Windows 8 if you report the company who illegally sold you this computer.
This is not true. Microsoft doesn't give a s**t about petty small-time builders screwing over individual users, just as they don't give a s**t about people who pirate their operating system. It's not worth their time. Their cash cows are office and their enterprise licensing for server, exchange, Lync, etc. Wasting time prosecuting small-time delinquents costs them to much money than leaving it be and updating their varying product activation and DRM implementations.
Secondly, it's a near guarantee that what she has installed on her computer is perfectly legitimate. What likely occurred here is something that has happened occasion for many years now: a pre-activated OEM image was updated or changed in some way that made it attempt to authenticate with Microsoft's activation servers. However the product key that is built-in to the OS is not capable of activation with those servers. It's not supposed to be activated. That's why it is
pre-activated in the first place.
With Windows 8 this was supposed to change with many OEMs. Individual product keys are generally imprinted in the BIOS/UEFI. Off-hand, I don't know if these keys and installations are still considered "pre-activated" or how many OEMs are actually doing this. I haven't really looked into it so I can't offer a solution besides reimaging the computer with the manufacturer's recovery manager (and not the Windows 8 refresh/reset options) but this has been an ongoing intermittent issue with prebuilt computers for a long while now.
