I’m not the person you replied to, but it’s great for telling you why the check engine light is on. If you’re somewhere that requires emission testing: you can diagnose if you have an exhaust leak, bad O2 sensor, clogged catalytic converter, etc. Besides that: its good just to know if the check engine light can be safely ignored.
For what its worth: I’ve been running enterprise since 2015 (when it was called LTSB) then switched to LTSC IoT around 2021. Its fantastic and doesn’t have all the Candy Crush and other bullshit. I highly recommend.
