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.

    SOLVED: (already tried clean boot; clean boot it unnecessary)

    1. Go to "Programs and Features." (via right-clicking on what the "Start Menu" used to be.)
    2. Select "View Installed Updates" on left-hand side.
    3. Find "Update for Windows 8.1 for x64-based Systems (KB2984006)."  (It is an optional update.)   [Also see note at bottom]
    4. Right-click and Uninstall it.
    5. Contact Microsoft and have them pay me for doing their job for them.

    Additionally you and can tell Windows Update to hide it for the rest of your life next time you see it there.

    Note: More recent experience made me realize is not just that update. There are multiple updates that cause this issue as I once again had to uninstall a different so-called "update." I personally have chosen to uninstall all updates not labeled "Important" and will not longer install "Recommended" or "Optional" updates as they are useless and seem to only serve the purpose of bogging down your computer and wasting space on your hard drive. Windows Updates are probably the only reason why computers seem like they are getting slower as time passes.

    Good Luck surviving with Windows OS!

    Unfortunately at least one "Important" update will case this error message as of 11 February 2015.

    Yes, this worked for me too. After reading your post, I installed the latest driver for my Genesys multi-card reader and then I reinstalled the problematic Windows updates. The ChangeIcon error message did not appear on restart.

    Thanks for your advice, BVR77.

    I have removed all three of the updates listed here and I still had the error, I then uninstalled all usb devices from device manager and rebooted, the error still showed. I am close to just doing a clean install, this is ****. Anyone with W8.1 care to share their dlls and exe? Maybe some of ours is just corrupted and we can get a working one.
