With a simple keystroke, freeware application Windows Hidie will hide those naughty windows on your desktop so you won't get busted looking at, say, Heidi Klum while you should be working. Call it the Cyber Slacker's ultimate must-have.
"When Windows Hidie hides a window, it disappears from your taskbar and from the Alt-Tab switcher, so essentially it's completely gone from the casual onlooker's view," according to lifehacker. "You can hide the active window with a quick stroke of Win-Z, show all hidden windows with Win-S, or toggle the display of the graphical interface to the program with Win-A. It's simple, does one thing, and does it well. Aside from what some might consider seedy uses, an app like this could also come in handy to keep apps running in the background that don't minimize to the tray."
