Summary

You can configure the following operating systems to write debugging information:

• Windows 7
• Windows Server 2012 R2

The debugging information can be written to different file formats (also known as memory dump files) when your computer stops unexpectedly because of a Stop error (also known as a blue screen, system crash, or bug check). You can also configure Windows not to write debugging information to a memory dump file.

Windows can generate any one of the following memory dump file types:

• Complete memory dump
• Kernel memory dump
• Small memory dump (64 KB)

Complete memory dump

A complete memory dump records all the contents of system memory when your computer stops unexpectedly. A complete memory dump may contain data from processes that were running when the memory dump was collected.

If you select the Complete memory dump option, you must have a paging file on the boot volume that is sufficient to hold all the physical RAM plus 1 megabyte (MB).

If a second problem occurs and another complete memory dump (or kernel memory dump) file is created, the previous file is overwritten.

Note

• In Windows 7, the paging file can be on a partition that differs from the partition on which the operating system is installed.
• In Windows 7, you do not have to use the DedicatedDumpFile registry entry to put a paging file onto another partition.
• The Complete memory dump option is not available on computers that are running a 32-bit operating system and that have 2 gigabytes (GB) or more of RAM. For more information, see Specify what happens when the system stops unexpectedly.

Kernel memory dump

A kernel memory dump records only the kernel memory. This speeds up the process of recording information in a log when your computer stops unexpectedly. You must have a pagefile large enough to accommodate your kernel memory. For 32-bit systems, kernel memory is usually between 150 MB and 2 GB.

This dump file does not include unallocated memory or any memory that is allocated to User-mode programs. It includes only memory that is allocated to the kernel and hardware abstraction layer (HAL) in Windows 2000 and later, and memory allocated to Kernel-mode drivers and other Kernel-mode programs. For most purposes, this dump file is the most useful. It is smaller than the complete memory dump file, but it omits only those parts of memory that are unlikely to have been involved in the problem.

If a second problem occurs and another kernel memory dump file (or a complete memory dump file) is created, the previous file is overwritten when the Overwrite any existing file setting is checked.

Small memory dump

A small memory dump records the smallest set of useful information that may help identify why your computer stopped unexpectedly. This option requires a paging file of at least 2 MB on the boot volume and specifies that Windows 2000 and later create a new file every time your computer stops unexpectedly. A history of these files is stored in a folder.

Windows 8 Server

This dump file type includes the following information:

• The Stop message and its parameters and other data
• A list of loaded drivers
• The processor context (PRCB) for the processor that stopped
• The process information and kernel context (EPROCESS) for the process that stopped
• The process information and kernel context (ETHREAD) for the thread that stopped
• The Kernel-mode call stack for the thread that stopped

This kind of dump file can be useful when space is limited. However, because of the limited information included, errors that were not directly caused by the thread that was running at the time of the problem may not be discovered by an analysis of this file.

If a second problem occurs and a second small memory dump file is created, the previous file is preserved. Each additional file is given a distinct name. The date is encoded in the file name. For example, Mini022900-01.dmp is the first memory dump generated on February 29, 2000. A list of all small memory dump files is kept in the %SystemRoot%Minidump folder.

Configure the dump type

To configure startup and recovery options (including the dump type), follow these steps.

Note

Because there are several versions of Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

1. Click Start, and then click Control Panel.
2. Click Performance and Maintenance, and then click System.
3. On the Advanced tab, click Settings under Startup and Recovery.

Note

You must restart Windows in order for your changes to take effect.

Tools for the various dump types

You can load complete memory dumps and kernel memory dumps with standard symbolic debuggers, such as I386kd.exe. I386kd.exe is included with the Windows 2000 Support CD-ROM.

Load small memory dumps by using Dumpchk.exe. You can also use Dumpchk.exe to verify that a memory dump file has been created correctly.

Volume definitions

• Boot volume: The volume that contains the Windows operating system and its support files. The boot volume can be, but does not have to be, the same as the system volume.

• System volume: The volume that contains the hardware-specific files that you must have to load Windows. The system volume can be, but does not have to be, the same as the boot volume. The Boot.ini, Ntdetect.com, and Ntbootdd.sys files are examples of files that are located on the system volume.

Registry values for startup and recovery

The following registry value is used under HKEY_LOCAL_MACHINESystemCurrentControlSetControlCrashControl.

• CrashDumpEnabled REG_DWORD 0x0 = None
• CrashDumpEnabled REG_DWORD 0x1 = Complete memory dump
• CrashDumpEnabled REG_DWORD 0x2 = Kernel memory dump
• CrashDumpEnabled REG_DWORD 0x3 = Small memory dump (64KB)
• CrashDumpEnabled REG_DWORD 0x7 = Automatic memory dump

Additional registry values for CrashControl:

• 0x0 = Disabled

• 0x1 = Enabled

• AutoReboot REG_DWORD 0x1

• DumpFile REG_EXPAND_SZ %SystemRoot%Memory.dmp

• LogEvent REG_DWORD 0x1

• MinidumpDir REG_EXPAND_SZ %SystemRoot%Minidump

• Overwrite REG_DWORD 0x1

• SendAlert REG_DWORD 0x1

Technical support for x64-based versions of Windows

Dumpchk Windows Server 2012 Service Pack

Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your x64-based version of Windows. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.
