Solve – com surrogate has stopped working in WINDOWS

com surrogate Error 

        “ COM surrogate has stopped working ” an irritating pop-up appears while watching some interesting photos or Videos. Here I had shown two ways to Fix the COM surrogate error. no need to go with any change of codecs ( Nero & DivX ). 

Process explanation: 

In a NUTSHELL, “COM Surrogate” is DllHost.exe process created by any other process, which wants to execute some code from any DLL (code library), but it doesn’t want to execute the code in its own space since it does not trust the code in terms of stability. So it creates a “surrogate” to execute the code. If that DLL code dies during execution, the only DllHost.exe surrogate process dies (giving us this “COM Surrogate has stopped working” error) and the initial process still alive. If this killing code were executed in the initial process directly, then the initial process dies instead of a surrogate.

Though actually, we have no need to care what it is and what all this means and how things work. We want our photos and Videos being shown.

 Other Ways to Solve ” Com surrogate Error ” Chosen from the comments: 


Problem: My Windows 7 x86 (32bit) Virtual Instance on Parallels Mac was having issues with launching Internet Explorer 11 after a forced upgrade from Internet Explorer 10. And since one of the websites needed for work rely on and are only compatible with Internet Explorer, this was driving me nuts. Every time I would launch Internet Explorer, I would get bombarded with a series of COM Surrogate errors that would never stop until I had ended the tasked via Task Manager and/or restarted the virtual machine.

Diagnosis: After attempting all the currently available solutions on the internet..: Updating Windows 7/8 Codecs, Adding Data Execution Prevention (DEP) entries for both COM Surrogate and Windows Host Process for my x86 Windows 7, Running an Antivirus scan, attempting to find a way to downgrade Internet Explorer 11 (nearly impossible), and even removing my Parallels Display Adapter form the Device Manager..

HERE IS THE SOLUTION that worked for me:
1. Hit Windows + R (Run) and launch “inetcpl.cpl” (Internet Explorer Settings)
2. Go to the Advanced Tab, and Click “Reset…”
3. Check “Delete Personal Settings” and click Reset. Tada!

Enjoy 🙂

  1. One of method worked for me, i would like to share that it might help someone else.
    Using OS: Windows 8.1 pro 64bit
    The Com surrogates stopped working error was faced everytime i was going to pictures folder from “Start Menu” and clicking on “Pictures”. The Pictures shortcut link was opening the pictures folder as “Apps -> Pictures” with a long random characters in address bar. Instead when i clicked my normal pictures shortcut, it simply takes me to C:Usersusernamepictures and the com surrogates problem was didn’t occurred that way.
    So I simply changed the “pictures” target location to “C:Usersusernamepictures” and problem got solved.

  2. are there alternate key for window key + Pause Break ,because COM Surrogate doesnt let me open it
