Are we unwittingly complicit in licence theft?

While preparing a vulnerable windows machine for HackTheBox, the question of what happens to the licence of windows machines came to my mind.

How are Windows machines licensed? Could you please inform us, the content creators, about this in more detail?

If HackTheBox is doing this without a licence, I don’t want to be a contributor.

Thank you

probably best to ask the staff for this one.
