How to Manually Initiate a Stop Error and Create a Dump File

To be absolutely certain that a dump file will be created when a Stop error occurs, you can manually initiate a Stop error by creating a registry value and pressing a special sequence of characters. After Windows restarts, you can verify that the dump file was correctly created.

To initiate a crash dump manually, follow these steps:

1. Click Start and type Regedit. On the Start menu, right-click Regedit and click Run As Administrator. Respond to the User Account Control (UAC) prompt that appears.

2. In the Registry Editor, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters.

3. On the Edit menu, click New, DWORD (32-bit) Value, and then add the following registry value:
• Value Name: CrashOnCtrlScroll
• Value: 1

4. Close the Registry Editor and then restart the computer.

5. Log on to Windows. While holding down the right Ctrl key, press the Scroll Lock key twice to initiate a Stop error.

You cannot manually initiate a Stop error on a virtual machine that has virtual machine extensions installed.
