This can throw off even the most advanced Windows user. Setup is simple and you need only a few seconds alone on someone’s computer. When you get a chance, sneak over and right-click your pal’s icon to Internet Explorer or some other commonly used program. Edit the properties and change the target to: “%windir%\system32\shutdown.exe -r -t 00″ Now, every time your buddy tries to run IE, his machine will mysteriously restart — and your laughter will instantly result.
