    A Kernel Memory Dump contains all the memory in use by the kernel at the time of the crash.

    This kind of dump file is significantly smaller than the Complete Memory Dump. Typically, the dump file will be around one-third the size of the physical memory on the system. Of course, this quantity will vary considerably, depending on your circumstances.

    This dump file will not include unallocated memory, or any memory allocated to user-mode applications. It only includes memory allocated to the Windows kernel and hardware abstraction level (HAL), as well as memory allocated to kernel-mode drivers and other kernel-mode programs.
