ChangeIcon MFC Application has stopped working.

Since the last set up updateson 16/09/2014 for "Update for WIndows 8.1 for x64-based Systems (KB2976719), (KB2989647) and (KB2984006)", I have been getting an error everytime I start up my computer stating that "changeicon MFC application has stopped working". It states the issue as an "app crash" and that the relevant program is "UMonit64.exe".

I traced to program to its directory and ran all my virus/malware/etc scans on it and they all said it was fine. I then attempted to run the program and it came up with the same error that pops up on startup and a second error message saying it wasn't able to run because "ustor.dll" was missing.

I did a system restore to before I did the windows update and sure enough everything worked fine. I then ran the windows update again after restarting to complete the update the "changeicon MFC application has stopped working" error message started popping up again.

So my questions are:

  1. What is UMonit64.exe/ChangeIcon Application?
  2. Did my windows update cause the issue?
  3. How do I stop the error message from popping up everytime I start up?
  4. Do I need UMonit64.exe? I haven't noticed any programs malfunction when I click the "close program" option when the error message pops up.
  5. If I do need it, should I download the missing DLL file to fix it? If so where would be a safe place to download the replacement dll file?
  6. Anything else I need to know to fix the issue or whether future windows updates will fix it for me and I should just ignore it for the time being.

    dang.... i been having this issue for a year now.. it wrecks havoc with my AVS video converter software too causing it to crash.

    Turns out I happen to have a Asus G750 laptop too! So stoked that you guys found the issue with the Genesys drivers... I have been at this thread for a year now, glad i checked it today again..

    well... i did all that.. i still get the MFC error box on boot..

    I have the Asus G750..

    I uninstalled all 3 updates:

    1. KB 2995388
    2. KB 3000850
    3. KB3013769

    I then downloaded the Gensys 4.5 drivers, and clicked the .exe installer on desktop, it installed with no errors. 

    I then reboot fully. The error still comes up. 

    I have now tried one more thing I read, I have copied the "ustor.dll" file in my new 4.5 driver folder to c:/windows32 and c:/WOWsys64 folders. I will reboot again and see if this works.

    i think this was what finally solved it. on my last boot this is what i did.. and i didnt get the error anymore.

    try this FIRST.

    Search your hard drive for a copy of ustor.dll (this is the mass storage device driver for windows)

    Copy this and paste it in to the following folder  c:/windows/syswow64
