Windows 10: COM Surrogate high CPU usage

Hello

I saw many posts for COM surrogate using high CPU but never a case like mine.

Whenever i click end task,it restarts the process but it keeps it low under 2% CPU

Then every time i start Windows Media Player,both files go over 25-30% so i end up having COM and Windows Media player using 50-60% of my CPU


How can i fix this ?

:)

 

Cortana & COM Surrogate high CPU usage when Search or Start Menu is opened

Hi Ruth,

Thank you for suggesting these troubleshooting steps. Unfortunately, starting in a Clean Boot did not resolve the issue. I remember that there were some updates available prior to this issue (KB3156421 and KB3152599) and I didn't do any major changes to
the system.

One thing that I forgot to mention in my first post, is that the high CPU usage also sometimes occurs with the "Host Process for Windows Tasks" process too. It mostly happens with COM Surrogate, but this process shows up sometimes too.

Thanks!

 

COM Surrogate high CPU usage due to Microsoft Edge browser

Encountered the high CPU usage issue with COM Surrogate but unlike previous solutions posted on here a few years ago and on other sites there's no video file dllhost.exe seems to be constantly trying to access, when I look at dllhost.exe in Process Explorer
under the file handles it just lists system files and the Edge cache, yet COM Surrogate consistently takes up 10-12% CPU until I manually terminate the process, so it seems there is another issue with COM Surrogate high CPU waste that does not involve Windows
trying and failing repeatedly to cache a thumbnail for a troublesome video file. Even weirder is that when I open a folder in Explorer containing lots of video files COM Surrogate seems to do its job of caching thumbnails and then closes when it's done doing
so. Yet when COM Surrogate decided to start running on its own in the background it keeps running and running and doesn't terminate at all, until forced to do so manually.

Update: I have now isolated this specific problem to Microsoft Edge, the anomalous CPU usage (12%) occurs when I start Edge and does not self-terminate unlike COM Surrogate's normal process when it's auto-started to cache thumbnails. Possibly dllhost is
struggling with "C:\Users\[User]\AppData\Local\Packages\Microsoft.MicrosoftEdge_[profile]\AppData\User\Default\CacheStorage\CacheStorage.edb" or "C:\Users\[User]\AppData\Local\Packages\Microsoft.MicrosoftEdge_[profile]\AppData\User\Default\CacheStorage\CacheStorage.jfm"
or "C:\Users\[user]\AppData\Local\Microsoft\Internet Explorer\CacheStorage\edb.log" if this Process Explorer method is indicative of the problem but this may be something else entirely, but it is related to Edge because the issue only arises when I start Edge
and not when COM Surrogate starts by itself to cache thumbnails, in which case it self-terminates normally when done.

To be clear, ~11% may not seem troublesome but it definitely is when it is CONSTANT. Meaning it does not stop even when I close Edge and has to be manually terminated, I only started looking into this when I noticed my CPU fans running faster consistently
for the past few days or week perhaps. I'm unaware if this anomalous behavior of COM Surrogate also occurs by itself (not triggered by starting Edge) but I will keep an eye out in the coming days.

I have run sfc /scannow (came up 100% no file corruption) and multiple full virus scans with F-Secure and Malwarebytes before posting. This seems like a new bug with Edge and COM Surrogate possibly.

 

high cpu usage

After downloading windows 10, anytime I run any programs, I get high CPU usage. It does not matter whether it is google chrome, task manager, playing games, whatever. Anything seems to spike the CPU usage. I have already run malwarbytes and my antivirus
programs and find no viruses. Any suggestions? Thanks.
