     guys if you should ever be forced by a robber to withdraw money from an ATM machine, you can notify the police by entering your Pin # in reverse 
     For example if your pin number is 1234 then you would put in 4321.
The ATM recognizes that your pin number is backwards from the ATM card you placed in the machine.
The machine will still give you the money you requested, but unknown to the robber, the police will be immediately dispatched to help you. 
     This information was recently broadcasted on TV and it states that it is seldom used because people don't know it exists.

With this you can create and invisible folder that you can put on your desktop or withing another folder. You can't see it but if you know where it is you can double-click it and view its contents.

1. Right click where ever you want the invisible folder to be, go to new, then click on folder.
2. Turn numlock ON, select the name, and hold Alt and press 0160, then release Alt. This should make a character that looks like a space, but it isn't.
3. Now right click the folder you just made and go to properties. Then go to the Customize tab. Then press the Change Icon button. Scroll through the icons until you find one that has no image (a blank space in the icons, any one will do).
4. Hit OK and you have an invisible folder!

Now you can put anything you want in there... If you can't find it, just select the entire folder/desktop and there will be a little blue rectangle below the invisible icon (the folder).

If you put it on your desktop it might show the folder for a second or two upon startup. For this reason I recommend putting it inside another folder.
