I had an application crashing on my Windows 7 system and couldn’t find a resulting DMP file anywhere. After some fruitless Googling, I finally found the magic incantation that I needed to get the Windows Error Reporting mechanism to write out a dump for me.
The trick for me was the DumpFolder registry value, described here:

Setting this value to a path on the local machine and setting the DumpType value to 2 finally got me the crash dump that I was looking for.
