okay, i should have been more specific. how would one activate an LTSC installation? last time i looked into it, you could not actually purchase a single LTSC license as an individual user.

Those are trial versions. You cannot fully activate them without doing the equivalent of a full OS install. You need to find a corporate partner and buy a whole bunch of regular Win 10/11 Pro licenses and you're eligible to get LTSC which costs a fair bit of money.
