This setting allows the system to reduce the pagefile size below the size of the RAM.
Before, the default dump type was "kernel" which sets a pagefile size to be "equal" to the size of RAM.
Now, if the dump type is set to "automatic", the initial size of the system-managed pagefile can be smaller than the size of RAM. Should a crash occur and the pagefile is large enough to contain a kernel dump, then a kernel dump will be written. Otherwise you'll get a minidump.
