Background information
While Windows XP came out I heard about a testing feature that existed to manually cause a BSOD (Blue Screen Of Death). I also heard this was supposed to be removed in XP Service Pack 2. It didn't get removed. It's also in Vista, Windows 7, and all later Windows versions. To enable the feature, navigate to this Registry location:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters
Add CrashOnCtrlScroll
as a REG_DWORD
with the value of 1.
Next, reboot. Finally, press Right Ctrl+Scroll Lock+Scroll Lock on any PS/2-compatible keyboard. You'll get a BSOD.
My question
Why is this feature still here?
