Forcing Windows to Crash

You can force Windows 2000 and XP to display the blue screen of death. Hopefully, the only reason to do this is that youll never see it otherwise! In the Registry key HKEY_LOCAL_MACHINESystem CurrentControlSetServicesi8042prtParameters, find or create a DWORD value named CrashOnCtrlScroll. Double-click on the value and set its data to 1. Restart your computer. Now you can cause a crash by holding the right-hand Ctrl key and pressing the Scroll Lock key twice.

Actually, a valid reason to crash your computer deliberately is to test your recovery options. Windows 2000 and XP can be configured so that in the rare event of a crash, a memory dump will be saved for debugging purposes and your system will restart automatically. If your system needs maximum uptime, it behooves you to verify how well it recovers from a crash.

First, make sure the recovery configuration is correct. Right-click on My Computer and choose Properties, then click on the Advanced tab. If you are running Windows XP, click on the Settings button in the Startup and Recovery pane. If youre running Win 2000, click on the button titled Startup and Recovery. In the System Failure pane youll generally want all three of the following options checked: Write an event to the system log, Send an administrative alert, and Automatically restart.

If you choose the 64KB Small Memory Dump, each occurrence is written separately to the folder specified. The Kernel Memory Dump is larger, and a Complete Memory Dump requires that you have a paging file large enough to hold all physical RAM plus 1MB; this is the largest option. By default, the two larger options are written to the file Memory.dmp in the Windows folder, with each occurrence overwriting the previous. Once you get the settings as you want them, close any open programs and use the special keystroke to crash the system. You can verify that the desired memory dump is written and check how long it takes to restart after a crash.
