Crash Windows xp(a bug or a silly feature)

There is very unknown way of crashing windows Xp.Even i was wondering how Microsoft can left such a silly function in their most popular Operating System.But that's not our business to mind.Let's start........

Windows-XP has a "feature" (???) with which it is possible to manually crash a system by simply holding the right CTRL key and pressing the "Scroll Lock" key twice.
This feature by default is turned off(thank god) but can be turned on by the following these simple steps:

1. Start regedit.(go to start and type regedit and press enter)

2. Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters

3. Create a new DWORD value and name it CrashOnCtrlScroll

4. Right-click on this newly created value and click on Modify

5. Enter 1 in the Value data field and click on OK.

6. Close regedit and reboot your system.

7. Now you can see a  blue screen of death(crash) by holding the right CTRL key and pressing "Scroll Lock" twice
.
TIP:Your system may reboot or show a blue screen whenever this crash is initiated. If your system reboots after initiating the crash, and you want to see the blue screen, follow these steps:
1. Go to Control Panel > System
2. Click on the Advanced tab
3. Under Startup and Recovery, click the Settings button.
4. Under System failure, uncheck the option Automatically restart.
Keep crashing your windows xp..
