This is a way to generate BSOD for testing.
You could use the following Microsoft “hidden feature” to force a BSOD:
To enable this feature, add the following value to the registry key HKLM\System\CurrentControlSet\Services\i8042prt\Parameters
* Name: CrashOnCtrlScroll
Data Type: REG_DWORD
Exit Registry Editor, and then restart the computer. When holding down the right ctrl and pressing the scroll lock twice at the same time Windows will generate a BSOD. You could test Virtual Machines High Availability etc with this.
