Why does dllhost.exe Com surrogate consumes memory untill crash

Well said mraroid.  You were more persistent than me.  But the solution was identical.  Later, however, IE10 did install... and the KD....838 was not installed, and my 3D memory loss continued to stay away.  I'm suspicious that it is 100% MS... since I know other Windows users who don't have the problem, and work with 3D files.

Thanks for the report.

I am ruining a Intel SATA 3 motherboard, 16GBs of memory, and a water cooled Nvidia GeForce GTX 590 video card.  My power supply is made by PC Power and Cooling. I am running Windows 7 Ultimate.

I had my 3D problem referred to Second Tier tech support at Microsoft. At first, I was told I have viruses and such.  As I run two or more anti virus programs at least twice a day, I did not believe this, but I let Microsoft run Viperescue, TDDSSKiller, Esetsmartin Hitmanpro_36X-64, and Malwarebites.  I still had my problem.

Then I was told I needed to have Windows 7 installed again as one of my programs corrupted Windows.  So that was done.  I still had the problem.  So I was told that I needed to create a new "user" ID which they did.  That did not fix the problem.

I had the following issues:

1. 3D files would not copy from one part of my hard drive to another - they would just hang.
2. If I went in and out of "computer" or "Control Panel" a few times, when I went back in they were blank - empty.
3. I received out of memory errors and had to reboot often.

After working with the Second Tier Microsoft tech, and letting him do all of the above,  I suggested it might be a Microsoft problem and that maybe it could be fixed if we un installed KB2670838, and did not upgrade to IE 10 (I am running IE 9).

After the Second Tier Microsoft repair person un installed KB2670838 and rebooted, all of my problems went away.  He re installed KB2670838 the trouble came back.

It was only then that he was convinced that is was a Microsoft problem.  I pointed him to this Microsoft discussion forum where Microsoft said "it is a virus".  He finally agreed with me that it was a Microsoft issue.

I told him the 3D community has been trying to alert Microsoft to this issue since at least April of 2013 (if not earlier), and it is now Dec of 2013.  And to date, Microsoft says it is not a problem with it's KB267083 update or IE 10.

The Second Tier Microsoft guy and I worked from about 10:30 AM one day, to about 6PM that night (while everything else was tried), and then we worked again a second day for a couple of hours.

He told me he would write it up and forward this information.  But he said Microsoft has no ability to get back to him if they found a fix, or if they decide to blow him off or not.  He can only send it up the line.

This is extremely poor service from Microsoft.  When 100s of people on 3D forums all over the world find and describe this problem to Microsoft and they blow all of us off by telling us we have a virus, it drives us to Apple.

I was lucky that I had a knowledgeable Microsoft Second Tier support person who knows how to read error logs and was able to see the problem himself and was able to see what happened when KB267038 and IE 10 was removed.  He was logged into my computer the entire time (both days).

He was frank with me in telling me that he will never know the outcome of this. 

All I can say to Microsoft is that if you wonder why we are moving to ubuntu or OSX, this is one reason why.  Your company is like a dinosaur and moves slowly to fix problems, if at all.  Shame on you.

Do the right thing.  Fix this issue and post here when you have a solution.

Sincerely,

mraroid

I had this issue too, and found a couple of workarounds.

You can solve it simply by disabling thumbnails, but this stops thumbnails for images, which I find quite useful.

A better solution is to disable the video property handlers - see this post

http://superuser.com/questions/152272/how-do-i-disable-video-thumbnails-in-windows-7

I found the problem its MS Internet Explorer 10 update.

I put in My old HDD and checked My problem files being the 3D Video files and I had no problems.

Then I started to allow Windows to update, when I got done with installing IE 10 and the restart.

The problem was there, So I did a system restore before the update to IE 10 and the problem went away.

Good luck Hope every one has a restore point or you may be able to manually uninstall IE 10.

For the time being Im going to use Fireox for security reasons being as IE 10 is a security update.

By the way Im going to start a new thread called Why does thumbnails crash after installing IE 10.

Also be aware of this update the link is here.http://support.microsoft.com/kb/2670838?wa=wsignin1.0%2cwsignin1.0

It also goofs with your codecs and video API's

Thanks a lot, uninstalling  update 2670838 solved my problem.

I had the same problem, no viruses.

BUT since I was lucky to notice it happend the "last" days after some program installations I did this:

1. uninstall al the last programs. In my case I was suspecting a JAVA UPDATE Installation.
2. Make o folder on your desktop and move/put in there all the shortcuts you got on your desktop.

[This measurment might not be needit but I did it]

3. Perform a Registry Clean with a tool like Windows Utilities or something else. Not a Registry defrag, but a Registry Clean. Do it 2-3 times to get rid of all broken links. The point is that dllhost.exe propably is searching something that it ain't no more...

Restart the PC

I solved my BIG problem with the above methods.

Always

a) Watch your computer status with Cpu Meter to see what's going on and

b) always after pressing Ctrl+Alt+Delete see all the tasks running and indexedthem according 1st their cpu usage  and memory usage.
