Windows 7: Dllhost.exe uses an enormous quantity of RAM

Ok

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.

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

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.
