Windows RDP, multiple sessions per user are turned on..

I always fall into one of existing sessions with all the crap left opened by my coworkers.. I'm fuckin sick of this shit, noone closes things after they stop using servers.. // the rant part

Is there a way to force new session on connect? // the question part

I tried googling but either I'm blind or don't know what to google.. only managed to find how to connect to specific existing session.. :/
