The Machine Memory Dump Collector - Windows 7 and Windows Server 2008 R2 diagnostic package was designed to collect machine memory dump files from a computer. This diagnostic tool collects both full or kernel memory dump files (Memory.dmp) and the last five machine mini-dump files from the past 30 days. The tool also collects related information. Machine memory dump files are limited to a size of 8 gigabytes (GB).
The following tables describe the information that may be collected from a computer when you run the Machine Memory Dump Collector - Windows 7 and Windows Server 2008 R2 diagnostic package.
