In Windows 8 and Windows Server 2012, Microsoft has introduced a new Memory dump option called “Automatic Memory Dump”. This is the default option set in the operating system.
For those you don’t know, on Windows 7 we have Minidump, Kernel dump and Complete Memory dump. You might be wondering why Microsoft chose to create this new Memory dump setting?
Well, according to Robert Simpkins, Senior Support Escalation Engineer, Automatic Memory Dump is to create support for “System Managed” page file configuration. The System Managed page file configuration is responsible for managing the page file size - therefore it avoids over-sizing or under-sizing your page file. This option is introduced mainly for PC’s that run SSD’s, which tend to have smaller size, but a huge amount of RAM.
