A. Win2K includes a feature that lets you crash the OS by holding the right Ctrl key and pressing the Scroll Lock key twice. To enable this feature, perform the following steps:
- Start regedit.exe.
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\ Parameters.
- From the Edit menu, select New, DWORD.
- Enter a name of CrashOnCtrlScroll, and press Enter.
- Double-click the new value, and set it to any nonzero value (e.g., 1). Click OK.
- Close regedit.
- Reboot your system.
Now, when you hold the right Ctrl key and press the Scroll Lock key twice, the system will crash and display a bug check code of MANUALLY_INITIATED_CRASH (0xE2). This keystroke combination works in some situations where Ctrl+Alt+Del has no effect.
