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:

  1. Start regedit.exe.
  2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\ Parameters.
  3. From the Edit menu, select New, DWORD.
  4. Enter a name of CrashOnCtrlScroll, and press Enter.
  5. Double-click the new value, and set it to any nonzero value (e.g., 1). Click OK.
  6. Close regedit.
  7. 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.
