tells you what running on your system

cool little tool, I get a new cool PC tool each time I buy that mag, them and maximumpc

How does it differ from Windows Task Manager?

It's a handy tool and beats having to type in a running process into Google to find out what it does. I have no idea what DLACTRLW.EXE is but when I highlight it and choose to view info via the web - it tells me :)

Saves me time
