    Can all you wonderful debugging experts take a look at this for me?

    Another heap corruption issue, though a little different than another of the "explorer crashing with heap corruption" threads around here.

    No obvious evidence that it's in any way linked to FF. In fact the only non-default modules at the time of the crash were from "Live Mesh", "MS Security Essentials", and Zune (which is new and therefore presumably blameless for sure).

    Out of curiosity, you haven't "modded" Explorer.exe in some way, have you? It's got a slightly newer timestamp and a slightly different size on your machine than it ought to for an RTM (7600) box:

    Did you perhaps use some sort of resource editor to patch/change Explorer UI elements? Otherwise, it's possible it was updated by WU, but it's strange that there's no symbol for that version of Explorer.exe on the MS symbol server.

    I'm not accusing, just trying to understand :)

    I'm very grateful for you taking the time to look mate, thank you.

    Nope, I have not modded or touched Explorer in any way.
    I did get an update from WU around a week or so ago.

    I installed from an original verified Ultimate ISO from my Technet account.

    How very odd, I really can't understand why my Explorer would be different, I tend to steer clear of any form of modding, tweaking, or resource editing.

    So what can be done about 'heap corruption'?

    Just been reading two other posts regarding heap corruption, I am gonna try your additional debugging instructions there.

    Excellent thanks. This was the thread which I was referring to, although it's probably obvious:

    https://www.sevenforums.com/crashes-d...-crashing.html

    That poster has an issue which - on the surface at least - appears very similar. Unfortunately, heap corruption problems are notoriously difficult to diagnose because the crash happens long after the "corruptor" has done its business and silently disappeared. That's not to say that the crash is deliberately malicious; the vast majority of heap corruption issues are caused by unintended bugs, sometimes in thread synchronisation.

    What's different is that you can seemingly always repro (unlike Porkrinds), so the root cause may be slightly different. It would be great if you could briefly enable extra "heap scrutiny" as per this post, and hence generate some more dumps:

    (And you can use the "cscript adplus.vbs..." method to generate the dumps from now on - two posts above that one.)

    I'm on the same boat here too.
    I get the same mmc.exe and explorer.exe crashing, both on Vista 64bit and 7 64bit.
    I'm at a loss and ready to pull out my hair.

    I haven't disappeared.. I get a similar freeze with the debugger when I catch a crash.. also, my computer seems to like behaving when I run it :\ but when I nab one, I will contribute to pile.

    You should start your own thread. you will get alot more response.

    Just a friendly heads up

    i had this same issue and it randomly vanished for me... tho i did perform most of the suggestions already and start uninstalling programs 1 by 1 to see if it solved it and it kept occurng until one random day it decided to just stop after disabling all context menus and uninstalling a load of progs. im about 90% its a context issue with something built into windows 7 that Microsoft has not admitted to just yet. all of those who think its a FF issue is extremely mistaken as FF does not alter windows in any way like they stated. also if everyone who experiences this issue uses any registry cleaner of any kind i would advise you reformat and avoid using that as one person seems to have claimed win 7 manager caused it after a registry clean/defrag. and myself have only experienced issues even from the better quality and known registry cleaners multiple issues after usage.

    Could it be drivers? It makes a little bit of sense, since I don't get the crashing on Windows XP 32-bit, but I get them on Vista 64-bit and 7 64-bit.

    You should consider starting your own thread if you'd like to work on troubleshooting the issue. There's nothing to link your problem to the OP's except process names.
