Hi friends, this trick is a small prank to play with your friends and make them worried. Using this trick, you can disable TURN OFF option in windows and even it disables ALT+F4 keys shortcut also. So, lets do this trick:
> Open Registry Editor
> Now, locate this key "HKEY_CURRENT_USER>SOFTWARE>MICROSOFT>WINDOWS>POLICIES>EXPLORER"
> Now, in the right side, right click and create A New DWORD Value with name NoClose.
> Now, double click on your newly created NoClose DWORD value and give Value Data 1.
> Done. Restart your PC.
Now your TURN OFF option is disabled and you have successfully made this prank. To enable the TURN OFF option again, just delete the key which you created in the registry editor.
