In this episode of Defrag Tools, Andrew Richards, Chad Beeder and Larry Larsen walk you through Sysinternals Desktops. Desktops allows you to organize your applications on up to four virtual desktops. We go under the covers and show how Desktops fits in to the Session, Window Station and Desktop object/security model.
** I didn't do a great job explaining Sessions/Window Stations/Desktops -- If you want to know about those concepts in detail, I suggest you watch Sysinternals Primer: Gems instead.
