Windows 7 has so many features that it is very hard to come across a specific one... Now this is the feature which i triggered by mistake...! Honestly it was just a mistake and when i searched the net, i found that it was a feature known as Aero Shake.

What it does and how do i use it?

Suppose a lot of windows are open on the desktop and you want to minimize all the window except one. Can you do that in Windows Vista? No? In Windows 7, it is possible. Drag the Windows which you want to be open and shake the window while still dragging it on the screen. All the other windows would vanish!

Now what do i do if i want all the windows back? Drag and shake the opened window again... and whoof...!! all the windows are back! Scary! Was my first reaction! lolz...! Pretty exciting!
