Windows 10: COM Surrogate using too much CPU, Thumbnail and Icon problem.

Hey guys i've been using Windows 10 for almost a month now, and I'm having some issues with it at the moment. I have too much videos and picture for work, that most thumbnail just won't load or generate.

Issues:

• Thumbnail not generating
• This PC/My Computer keeps loading and saying "Working on it" (File Explorer)
• High CPU usage for COM Surrogate, using 10% of my CPU all the time.

The way to solve it for me at the moment is killing the COM Surrogate process. But I'm looking for a permanent fix, which doesn't involve me killing the process all the time.

Killing the process of COM Surrogate will make:

• Thumbnail and icon to generate (although sometimes it still doesn't)
• This PC/My Computer instantly loads properly, without it saying "Working on it"

Any solution guys?

Com surrogate consumes all the memory memory

Hi,

The dllhost.exe process goes by the name COM Surrogate and the only time you're likely even to notice its existence is when it crashes and you get the message COM Surrogate has stopped working. What is this COM Surrogate and
why does it keep crashing?

The COM Surrogate is a fancy name for Sacrificial process for a COM object that is run outside of the process that requested it. Explorer uses the COM Surrogate when extracting thumbnails, for example. If you go to a folder with thumbnails enabled,
Explorer will fire off a COM Surrogate and use it to compute the thumbnails for the documents in the folder. It does this because Explorer has learned not to trust thumbnail extractors; they have a poor track record for stability. Explorer has decided to absorb
the performance penalty in exchange for the improved reliability resulting in moving these dodgy bits of code out of the main Explorer process. When the thumbnail extractor crashes, the crash destroys the COM Surrogate process instead of Explorer.

In other words, the COM Surrogate is the I don't feel good about this code, so I'm going to ask COM to host it in another process. That way, if it crashes, it's the COM Surrogate sacrificial process that crashes instead of me process. And when it
crashes, it just means that Explorer's worst fears were realized.

In practice, if you get these types of crashes when browsing folders containing video or media files, the problem is most likely a flaky codec.

Perform SFC(System File Checker) scan and see if it helps.

a: Press Windows key + X.


b: SelectCommand Prompt(Admin).

c: Type SFC / scannow
and hit enter.



Please reply if you have any questions.

 

You could try Shark codecs:Windows 10 codecs - Windows 8.1 codecs - Windows 7 codecs

 

Does the icaros thumbnailing solve the issue? I'll try that standalone icaros thumbnailing and see how it goes.
I'm currently using Media Player Classic with combined community codec pack.

Edit: Looks like using Icaros solves the issue. Less CPU usage from COM Surrogate, and generating thumbnails instantly like on Windows 7 and 8.

 

Your player is incompatible with your system. I just solved this issue by uninstalling 32 bit VLC Player and installing 64 bit version.

 

Thanks! I did this and it took care of the problem!
