Windows feature lets you generate a memory dump file by using the keyboard
This article was previously published under Q244139
Windows includes a feature that you can use to cause the
system to stop responding and to generate a memory dump file (Memory.dmp). When
you do this, you receive a Stop error message that resembles the
following:
*** STOP: 0x000000E2
(0x00000000,0x00000000,0x00000000,0x00000000)
The end-user manually
generated the crashdump.
After you enable the feature, you can
generate a memory dump file by holding down the right CTRL key and pressing the
SCROLL LOCK key two times. The feature is available for both PS/2 and universal
serial bus (USB) keyboards. PS/2 keyboards use the i8042prt.sys driver that is
included with the keyboard. However, for USB keyboards that are attached to
Windows Server 2003-based systems, you must install a hotfix for the Kbdhid.sys
driver.For more information about this hotfix, see the resolution in the "More Information" section.
Note There is a limitation with the Kbdhid.sys driver that allows for you to generate the memory dump process by using a USB keyboard. The CTRL+SCROLL LOCK+SCROLL LOCK keyboard shortcut does not work if the computer stops responding at a high interrupt request level (IRQL). This limitation exists because the Kbdhid.sys driver operates at a lower IRQL than the i8042prt.sys driver.

(http://msdn.microsoft.com/en-us/library/ff545499.aspx)
Note The USB keyboard feature can be used in Windows Server 2008 if Service Pack 2 or later is installed, or by installing the following hotfix:

(http://kbalertz.com/Feedback.aspx?kbNumber=971284/
)
A hotfix is available to enable CrashOnCtrlScroll support for a USB keyboard on a computer that is running Windows Vista S971284 or Windows Server 2008

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
