Thanks. I have been viewing this forum for years already, but always found what i was looking for and have done many tweaks found from here, so thanks for the good stuff

Are these image files very large in file size? If so, when there's a lot of them in a single folder, it could cause a delay in loading their thumbnail previews, or not even load at all.
Well i dont know ... big and small, all the image files seem to do that. I noticed this quite soon after starting to use Win7, cause i dont remember ever having this problem on XP. ... cant be sure tho. I first noticed this when scrolling fast a big folder, like camera's memory card, which contains about 5-6MB files usually, but they loaded anyway, so i thought this was just one more "fix it till its broken" Win7 bugs, but now when it started to stop loading the thumbnails completely, even with slow scroll it started bother me.

You might see if resetting the thumbnail cache for now may help if it may be corrupted.
I will try that now...

Nope, that didnt help. I wonder what it is...? Images that i saved just now on desktop show as thumbnails, but older images doesnt. ... looks like not all of them, haha, that would have been simple :P If i copy /paste a thumbnail image, the pasted image doesnt show as thumbnail.

Odd. As a test, rename one of the old images you copied to the desktop to see if it shows it's thumbnail afterwards. You may need to refresh (F5) the desktop afterwards though.

Are these images on a local drive, or one from a network location?

Any place ... Desktop is of course on C: but camera's memorycard is USB ... but no difference.

To make this more fun (haha) i just tried to browse same locations with Photoshop, and it shows the thumbnails just fine, and a lot more faster than Explorer does. Also tried with REALLY old Animation Shop 3 (looks like 2003) and it shows thumbnails in realtime, no lag ... ok, if i scroll REEALLY fast then it shows some lag but i would say fast.
This seems to be a Windows Explorer problem ... hmmm...

Yeah, explorer never was very good with thumbnails when there's a lot of them with large file sizes.

You might stick to viewing them with those programs, or use an explorer alternative like FreeCommander.

Thanks. I think it was something i have done in a few days cause it started maybe 2-4 days ago. I will keep finding the fix, and let you know if i do.

If you like, you could do a system restore using a restore point dated before this happened to hopefully undo and fix it.

That didnt do anything,but hey i fixed it!!!
I noticed that dllhost.exe uses a lot of cpu so i started to search that, and then i found this
Windows 7 dllhost.exe memory leak - Microsoft Community

3rd post says "The cause is probably an error in the integrated mp4 windows codec..."
Well i didnt install any Media Preview
cause i remembered that i have a mp4 video file on desktop that didnt convert properly and when i tried to delete it, it couldnt be deleted "because some mysterious program is using it" haha. I have so much work that i have have time to think about that video file more, so i kind of forgot it.
Anyway, what i did was install MoveOnBoot MoveOnBoot Free - Rename/Move/Delete Locked Files on Reboot and deleted that bad video file and WOW, that did the job YAY, now the thumbnails load normally again!
I hope this help anyone who may have this.
