How to fix
“COM Surrogate Has Stopped Working” error
on Windows

I desperately need a fix for “COM Surrogate has stopped running” error. This annoying pop-up message appears on the screen whenever I try to open some media files or print something from the Internet.

Sometimes, it pops up at random times for no reason. I need a solution because I would like to use my computer without having to encounter such mysterious problems on a daily basis. Can you help?

“COM Surrogate has stopped running” is a common Windows error that keeps bothering Windows 7,8, 8.1 and 10 users. Usually, you can encounter it while browsing though videos or pictures on your computer. If you try to open them, the suspicious message pops up. Additionally, this error might appear once you try to use Control Panel or other applications.

COM Surrogate[ref en-1] itself is a legitimate Windows process also known as dllhost.exe *32. It is responsible for hosting one or a couple of system services and is used by many computer programs. It not only manages applications which are based on DLL but controls the operations of Internet Information Services (IIS) as well[ref en-2].

Actions performed by COM Surrogate can hardly be recognized by a regular PC user. However, the best example of its performance would be the thumbnails of the programs or files[ref en-4]. You can see the different images once you open a folder only because of this process which might seem unnecessary at first sight.

While COM Surrogate is not likely to be corrupted by malware, there is also a malicious version of this Windows process, widely known as COM Surrogate virus. This Trojan horse[ref en-3] disguises under a name of a legitimate Windows process and can significantly decrease your computer performance. Additionally, be aware that it might steal your personal information or other valuable data[ref en-5].
