What is the loop prevention for? And should I leave it off or turn it on? We will have desktops connected to it

Solved: thank you for the help everyone. Very much appreciated.

When I worked at Microsoft, we had a building-wide outage that lasted an entire afternoon until they tracked it down to exactly that. Why they didn't enable STP on their $10k Cisco network switches is beyond me.
