Why not just try the free upgrade hack? IIRC Ms still lets you activate with a Win8 key. Hell, I did it just at the start of the year with a pentium build I did.
Because if s/he installs it and the free upgrade doesn't work, s/he can no longer sell it.
@anastbogia1 - Personally, I'd consider it a lost cause as people can install and run Windows 10 (unactivated) for free, but there might be a buyer out there. EBay seems to list some sales, but I have no idea how recent they are.
