The two knights, albeit being forced to stay in place, still take away enough squares from the black king, especially to knight on e6, to allow white to easily win an opposition battle. The white king penetrates via the centre and gets an easy promotion, with enough tempi ahead of black. Try it yourself, it is really easy.
edit. meanwhile you posted a possible follow on yourself. Better than if anyone else had done it
edit 2: yes , this problem has been known to be a tough one for the computers too, with some exceptions. Most programs don't 'see' that the position is a simple endgame. That's why I challenged the term '100% tactic' in other threats. This is positional.
