Have a look into the thread with the EOL announcement for the legacy edition of Spiceworks.

No, inventory will not lose all its functionality immediately on New Year. You may continue using it. But if you did not prepare for continued operation as recommended in the thread, you may lose sooner or later at least some functionality. And so far, I’ve not read any feedback in that thread that any Spicehead would have run such preparatory testing steps, even not those intending to continue using it.

I recommend our field guides, especially those on getting started (in the community) and on pos(t)ing good questions, including the helpful references found at the bottom of its web page. I believe the field guides were published since you joined a decade ago.
