SW opens related files when openeing a part/assembly?

When I open and assembly or part with inserted standard hardware or assembled hardware SW opens them also.

SW pulls up my part and also the bolts and pins or whatever.

When I go to close my part or assembly I have to then close a bunch of windows behind the part.

How do I get solidworks to stop this as the other users here do not have this issue.

SW 2010. We do Not have PDM.

Thanks.
