Windows 7: dllhost.exe constant 50% cpu

12 Mar 2010   #11


Seems we didn't solve the problem.
I've got a solution to this. Just get an "content" view of the folder which contains flv files, things like this would not happen. But I can't solve it fundamentally, either.

However i still haven't found which file is causing the problem. Is there any way to find out?
Sorry for reply you with long time gone.
I think you can try to turn off thumbview of win7 then reboot to watch whether it come again.If it can not be solved,means your win7's problem is not cased by thumbnail.Can't help you,sorry.

Windows 7 Ultimate 64bit
I think I found something...

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

Win7 Pro 64

I am not able to move the wav file to another folder nor am I able to delete it using explorer.exe.

If anyone figures this out please reply.

Use the program Unlocker to move or delete the file.

Does anyone know what causes this though? Each time I render a wav file with Fl Studio now causes this problem.

With what settings do you export the wav?

I have a suspicion that this is codec-related.
