Dllhost.exe uses an enormous quantity of RAM

[RyanB]

But you still haven't and may never figure it out. After reinstall, do the folder "test". Also, do it after installing each program or change made to the system.

Ok

If you don't want reinstall, maybe you can circumvent the problem by changing the view settings of the folder to show list instead of icons.

It's already "list" but I tried other view, same things.

I'm thinking now, we can reinstall windows (not repair) without formating the partition, can't we ?

Thanks.

Yes. Whatever is on the partition will be moved to a folder named "Windows.old"

Or to format:

When you get to the screen asking where to install, click Advanced and (make sure it's the C drive) Format. It's quick, only a few seconds.

Ok I'll see that . I hope it will make a real reinstall, deleting the programm files & windows folders. But not everything in C. I put all my backup on a folder directly on C:.

I'm going to reinstall it now.

 

[bum]

NO! get your stuff you want to save off of the C drive or DON'T format.

 

[RyanB]

Don't worry bum, I didn't lose anything since I didn't make a formatting.

I reinstalled Windows and it is perfect now, I just chose C: without formatting, and that moved the old files of “Documents” “Programm Files” and “Windows” to a folder “Windows.old” and Installed a fresh new Windows. But I had already backup all my files in a C:\Backup folder. Because I knew that Windows was not going to remove what was created by me in the root of C:.

So it works perfectly now, I don't have any more all my problems:

- dllhost.exe
- startmenu disappearing
- key usb not recognized

(all those problems that I had since the beginning of my upgrading from Vista to Seven).

All is solved, even after having installed the antivirus (Kasperky), I still do not have the problem of dllhost. I will check each time I install a new software and keep you informed if I discover from where the problem came.

Thank you.

Most excellent...I will mark this thread as solved. If you have any more questions or concerns than please come back and post or start a new thread on the subject

For those of you who are still struggling with this I think I found something. I had some large audio files (and video files) on my desktop. Once I moved those to another folder, the locked 25% dllhost issue cleared.

Prior to that I tried these things which did not solve:
- Malwarebytes Full Scan
- Microsoft Security Essentials Full Scan
- System restore to 2 weeks prior
- Removal of K-lite (Base, Full and 64bit)
- Removal of Tversity
- Close all open programs using procexp

The below is me mostly copy and pasting what I posted in another forum for reasons I explain in the last section.

Fix that worked for me:
1. Install this thing: BabelSoft / ????
2. Once its installed, open it and go under file formats(it might go there for you), check all the video formats that you don't get thumbnails of in folders.
(For me I checked everything under flash video, MPEG-4 Part 14, and Windows Media)

Check if it worked
-Go to your video folder with the video files previously causing dllhost to explode, and the green bar thing at the top should finish, thumbnails should show up (if they don't go check off more things with the method explained above in 2.), and dllhost shouldn't explode.

I had a similar problem (same problem of dllhost taking up tons of memory), and found out that it was apparently caused by windows epic failing at making thumbnail previews. Thus, after hours of installing crap and trying other 'fixes' that didn't work at all, I tried downloading the extension linked above that previews thumbnails. I proceeded to do what I listed in the instructions in the top area of this post and dllhost didn't explode when I went into the folders that previously caused it to. Also, all of the thumbnails that previously would not load loaded, with the exception of one, but nonetheless dllhost didn't explode for that one, so I'm happy.

Posted here cuz this thread came up a lot when I searched for this problem, I've posted in the other thread that came up a lot for me when I searched for this problem too. If the fix works for you guys as well, please go ahead and post it in other threads that came up a lot for you when you searched. I wasted way too much time getting this fixed. >_>

After re-installing Windows 7, and the problem coming back again, I tried another approach, which is to download Nirsoft shexview, or ShellExView.

This allows you to disable shell handler properties. There is a section of Media Foundation handlers:

MF ADTS Property Handler
MF ASF Property Handler
MF AVI Property Handler
MF MPEG Property Handler
ETC

The one giving me the problem is MF MPEG-4 Property Handler

My shell no longer agonises over my folders. I feel you could probably fix a few problems this way.

I've had this problem before. I believe it's a Windows 7 error. When you have a large amount of files (mine have all been with mp4 videos) in the same folder, The COM Surrogate begins to "leak" memory. For me, it starts low, around 25% and then gradually builds to 100% and then eventually slows my computer to a halt. This happens even if I open the folder and then close it.

Essentially the COM Surrogate gets the job of making the thumbnail previews, has an error in it's coding, and becomes a memory leak, stealing your RAM from other potential uses.

I don't have any idea how to fix this. Does anyone have any thoughts? Most of the previous suggestions seem to be ineffective.

 

[astrayan]

That's why you use shex, to stop it making thumbnails for half of the types.

 

[Hondajt]

Why would I want it to stop making thumbnails? I just want to stop the memory leak. I thought maybe someone would know how to do that.

 

[haxan]

omg

wow im having the same issue with my laptop.
the memory goes to 98% and the only way for me to lower it ( temporarily) is by closing the dllhost from the task manager... so far this seems to help me.
also this problem happened to me after i downloaded couple of mp4 videos from youtube.... probably shouldn't have done that :/

 

[Hondajt]

This now seems to be happening consistently, whether I open a folder with large files or not.

Anyone have any ideas?

 

[kaelym]

same issue, when i open folder with lots of videos dllhost opens and uses millions of memory

 

[cradyro]

Just registered to post that this exact same issue is happening to me. It's only started happening in the past month or so, and the only change on my end is that I've been working with .mp4 videos a lot more frequently. (I've always done video editing but I've been using mp4s much more frequently for various reasons).

Same symptoms. dllhost climbs in RAM usage until it's consumed it all, then windows becomes completely unresponsive. The service
"Resource-Exhaustion-Detector" appears to leave an entry in the system log (Event Viewer -> Windows Logs -> System)
(See attached screenshot, or http://i.imgur.com/xFOP8fi.png)


Anyways, killing the dllhost process when this happens appears to temporarily fix it. But I can't reproduce exactly when the memory leak starts, it just always seems to happen when I'm dealing with mp4 video files.

I'm using Windows 7 Professional 64 bit.

EDIT: I should add that I've already tried running the System File Checker sfc /scannow, and windows reported no integrity violations with system files.

Try downloading and installing Process Explorer. It is a great program for figuring out what application or process is taking up all of the computers resources. Once it is running hover your mouse pointer over the dllhost that is causing the problem and it should pop up a box that will tel you what application is causing the issue.

 

[ldougherty]

I have the same problem. The process dllhost.exe * 32 is running on my PC and is using a large amount of both cpu and memory. I have killed the process several times and each time it comes back and slowly builds up using more and more cpu and memory.

I have other strange issues such as popups that look like windows warnings reminding me about FREE Computer Backups. I also had random Windows popups trying to prevent me from downloading process explorer.

Can anyone help me determine how to disable this task whatever it is?

Anyone?

The problem you have is called "MyPC Backup" get rid of it.
