I've been trying to debug why this error occurs. Unfortunately it does not generate a crash dump of any form. I've checked by doing Start > Run > "%allusersprofile%\Application Data\Microsoft\Dr Watson" next boot after this error, but there is no user.dmp. The most it generates is an item in the event viewer, which is as follows:

Application popup: Explorer.EXE - Application Error : The instruction at "0x7c9106c3" referenced memory at "0x7e29e356". The memory could not be "written".

I've updated fully and my explorer.exe is: 6.00.2900.2649

I believe the current/standard version is: 6.0.2900.2180

The only time I've seen this occur is when I shut down the computer. It's rare that it happens. Seems to be about once every 7-10 shutdowns.

Assistance is welcome.

Download and install userdump, create a rule for explorer.exe, and it will generate a dump everytime explorer exits (including good shutdowns, so keep that in mind). This is preferable, because it'll also generate a dump if it terminates unexpectedly, which is what you want.

Thanks cluberti!

I'll have to post the results of the dump next time explorer.exe crashes.
