There’s this song from Lazy Town. It goes something like “yarr harr fiddle dee dee”.
Either that or got a key off an admin (school, work, etc.)
There’s also a chance it was bought through less legitimate means.
In any case, it is harder to obtain than even the regular Enterprise version, but not impossible.
E: oh I completely misread the question. To obtain it, I believe it can be obtained via UUPdump or something like that directly off of MS.
I don’t think that’s gonna work because this is a thing that he needs
