From the developer:
ZHider is a tiny and easy-to-use utility that can instantly hide windows (programs) with a quick keystroke. Windows are hidden completely from view and from the task bar without a trace. Hidden windows can easily be brought back into view with another quick keystroke that toggles their visibility from hidden to visible.
You may want to check out more software, such as ToolbarCop or Discover It!, which might be similar to ZHider.
