I've used Mark Russinovich's #Sysinternals utilities for decades (autoruns, procexp, procmon, tcpview, etc.), but I properly learned about #ZoomIt only in recent few days (so late possibly due to deceptively simple name), which supports more than just zooming screen (BTW doable via Win+Plus without any additional software). Great little tool for sessions with screen sharing and presentations in Windows.
