I've seen that others are having similiar problems, but mine were occuring when i'd empty the recycle bin, or heading into explorer. so I wasn't sure if it was the same deal. Can anyone help

There are any number of reasons why a crash like that may occur, and most are related to the addition of 3rd-party code which runs "inside" the Explorer process - right-click menu context handlers and the like.

If you go through the following to obtain a memory dump generated during the crash, someone may be able to tell you why Explorer is behaving that way on your machine:

1) Download and install either the 32-bit or the 64-bit "Debugging Tools" package, depending on your OS type: Debugging Tools for Windows - Overview

2) Open a CMD prompt and CD to the folder where you installed the debugging tools.

3) Run this command:

cscript adplus.vbs -crash -noDumpOnFirst -miniOnSecond -quiet -pn explorer.exe

4) Reproduce the Explorer crash.

5) Find the new folder in that same location with a DMP (memory dump) file. Zip up that entire folder and upload it here.

This is the folder
Are you quite sure Explorer crashed after you did all that? Can you see a new event log entry corresponding to the last crash which happened after you issued the "cscript adplus.vbs..." command?

Are you saying that you can't seem to repro the crash after you run that command?

(The command by itself won't cause/reproduce another crash instance. It just sits there and waits for the monitored process to crash again, so that it can produce a (mini) memory dump.)

I'll give it a shot, but you'd be better off waiting for H2SO4 - I don't have any experience with user-mode dump files.

Sorry, but I just can't make much out of the download. I wonder about your Trend Micro installation - so you may want to uninstall it to see if that helps. But that's just a guess on my part.

Hmm, another heap corruption crash. I can't precisely tell you the cause based on that dump, but there are two possible approaches from this point onwards which will almost certainly lead to a resolution:

A) Remove the following Explorer add-ons one-at-a-time and test whether the symptom is reproducible without each one of them in turn: "FileLock", nvidia shell extensions, Bonjour, WinRAR (it has added a context handler), Trend Micro AV. My gut feeling tells me to blame FileLock as the most likely offender, but that's just personal bias. It could be any of them.

OR

B) Enable a special mode of operation specifically for the Explorer process, in the hope that the next heap corruption occurrence will be caught as it happens, rather than later on down the track when the bad data is accessed. The procedure:

1) On an elevated (run as admin) CMD prompt: gflags /p /enable Explorer.exe /full

2) Reboot or restart Explorer (same effect).

3) Once again, run the "cscript adplus.vbs...." command from before.

4) Reproduce the Explorer crash again.

5) Find the new DMP file, hopefully the small one with "2nd_chance" in its name, and upload just that for analysis.

Recreated the crash and dmp file (one that begins with 2nd chance) is attached

Did the process again just in case you needed a recent file.
