Calling a bluescreen in windows 7

Hi,
if you configure a client for creating a dump file and you would like to test this configuration (e. g. create no memory dump file or create a full memory dump file) you can manually call a bluescreen.
Start the registry with administrative privileges.
Then go to the following key:
HKLM\System\CurrentControlSet\services\i8042prt\Parameters
There you have to create a new DWORD-Value containing this:
Name: CrashOnCtrlScroll
Value: 1
After these step you can logon to your windows computer.
By pressing the right CTRL key and the scroll-key the bluescreen will be executed.
Have a nice day
Bye
