storeassetd trying to install software

I have seen this pop up a few times since Updating, and I'm very curious as to why no one at apple has answered what it is or what it does.

So... Apple, what exactly is storeassetd and what software is it trying to instal?

??

Also, after recent update all settings were wiped out, and new interesting named things in activity monitor like "trustd", several "MTLCompilerservice" processes, "IMAutomaticHistoryDeletionAgent", "bird"...
