Snadman.exe creates a dmp file when it crashes, this dmp file contains the execution state and a few parts of memory which were used by sandman.exe prior to the crash. you can not trigger a crash dump from the UI, but you could using 3rd party tools like task explorer or system informer
Thanks David. I was looking for a way to get more info like a dmp or log file in case I need to check or report an issue.
