    Random Explorer.exe APPCRASH??


    Hey all,

    Since the beginning of january I've been experiencing an occasional explorer.exe crash every once in a while. It has happened 3 times now and I have no idea what causes it. It occurs only when I switch rapidly from Dekstop to the Metro UI and then back to the Desktop again although this does not always provoke the crash. I can then see the taskbar restarting. Also, in every case I had Internet Explorer running on the Desktop. The crash is unpredictable.


    I haven't installed any drivers or software the first day the error occurred other than a steam tile app that I uninstalled the very same day.

    Here's the log of the crash:

    My specs:

    8 GB RAM
    1 TB HDD
    i5 3570K
    GTX 660Ti

    Any idea how to fix this?

    Thanks in advance,

    TwinUI is what allows Metro and Desktop to coincide on the same interface.

    Have you installed any start menu replacements? Have you made any modifications to system files (lots of people hack dll's to change things about windows they don't like).

    No I haven't installed any mods or modified any system files since I know they could cause problems. However, I just remembered that I ran a sfc/ scannow prompt 5 days before the first crash because of a BSOD I had back then. The SFC found and repaired the following files:

    000006fd [SR] Repairing corrupted file [ml:520{260},l:46{23}]"\??\C:\Windows\System32"\[l:16{8}]"mfds.dll" from store
    000006fe [SR] Repairing corrupted file [ml:60{30},l:58{29}]"\??\C:\Windows\SysWOW64\en-US"\[l:46{23}]"windows.ui.xaml.dll.mui" from store
    000006ff [SR] Repairing corrupted file [ml:520{260},l:46{23}]"\??\C:\Windows\System32"\[l:34{17}]"mfmpeg2srcsnk.dll" from store
    00000700 [SR] Repairing corrupted file [ml:48{24},l:46{23}]"\??\C:\Windows\SysWOW64"\[l:34{17}]"mfmpeg2srcsnk.dll" from store
    00000701 [SR] Repairing corrupted file [ml:48{24},l:46{23}]"\??\C:\Windows\SysWOW64"\[l:16{8}]"mfds.dll" from store

    Could these files have anything to do with the crash since they are modified by de SFC? Btw, I never had a BSOD since then.

    Have you run sfc since then?

    I did run it a couple of times (also after the explorer.exe crash) but it didn't find any corrupted files anymore.

    Well, here's the thing. If you had corrupted files, that could be a symptom of problems with your hard disk. That means that other files, like configuration files, the registry, etc.. might also be corrupted. These are files that sfc can't track because they are always being updated. You may be forced to re-install or refresh your system.

    Quite a heavy fix for this. Aren't there any other tools that can check for corrupted config files, registry and so on? Also I doubt that there are problems with my harddisk since the BSOD I had was referring to a faulty driver or a memory problem. I ran the windows diagnostic tool for memory problems back then but it didn't find any. :/

    windows diagnostic tool for memory is not a good tool, I was helping somebody in this forum and he ran it for 12 hours without finding any thing wrong then he switched to use: memtest86+ and found out that his memery was bad.

    Here is the link to download memtest86+

    @ topgundcp: Thanks! I'll try it out.

    @ cluberti: I found those links aswell, however I just noticed I skipped a line back then that exactly describes my problem (I think):
    "Explorer crashes while changing a desktop mode. But this is a MSFT bug that we can't fix. Contact the MSDN/Technet support"

    So I guess there's no fix for this other than contacting MSDN/Technet support...
