dllhost.exe Com Surrogate kicks off every few minutes - maxes out my i7 CPU - and steals the focus from whatever window I'm working in... and lasts for a couple of minutes.
The focus can be on any application (browser, notepad, etc.) when Com Surrogate runs and starts hurting me. It does not only happen when switching focus to a File Explorer window.
I do not get any kind of Com Surrogate error - just a really bad desktop denial-of-service.
I've tried all of the internet "fixes" I could find:
- Updated codecs - Disabled thumbnail creation - Did the DEP settings - Checked for malware with multiple antivirus engines - Process Explorer does not show any image or media file targeted by dllhost.exe
I think this Com Surrogate action is the CPU eating problem...
Process Monitor (different than Process Explorer) shows the dllhost.exe Com Surrogate process going through all of my disk folders every time it is eating my machine. It appears that it is still looking for media files to make thumbnails for - even though it doesn't actually create any thumbnails any more!
Also, how/why the non-visible Com Surrogate process is stealing the active window focus is beyond me.
(FYI... Com Surrogate has run, and maxed out my CPU, eight times while I was trying to type this question.)
Given that information, does anyone have anything new to try?
