Windows 7: Win 7 64 bit : Video thumbnail preview not working

Win 7 64 bit : Video thumbnail preview not working

I have folders set to "show large icons" and i have "always show icons, never show thumbnails" unchecked, but the thumbnails of video files always show the default program icons and never a preview of what the video contains.

Why is it doing this and how do i fix it?

Hello Question2 and Welcome to Seven Forums

The default program to play your videos might not support thumbnailed images for preview. What program do you have set to be the default for say Mpeg or Mov files?

The best way to get thumbnailed previews to work again is to go to the start pearl and type in "Default Programs" in the search bar. Choose "Set your default programs" then click on "windows media player" and give it all it's defaults. Reboot then see if the thumbnails preview for videos functions again.

If not then we can run a couple test to see if it might be another issue. I have run into this issue myself when I installed VLC player to view a video that would not play in Windows media player.

The default program is set to WMP.

Does WMP present a thumbnail of the video?

I agree with MohavePC on VLC. I updated to (I forget) version and all thumbnails, album covers were "broken". I had to roll back VLC to "fix" it.

Is this just videos or are Documents, Pictures and Music also affected?

Do you have the issue when you look in the Videos folder and when you look in the Videos Library?

Uh not sure what you mean but when i look at the icons in windows explorer, they all just show the generic video thumbnail instead of a preview of the video.

But images work just fine.

Have a look at this tutorial Default File Type Associations and follow the directions there. If still no love then I would suggest an System file check and perhaps a malware scan..

Could you post a screenshot of the files in question so we can see the default "generic" video thumbnail you speak of? sometimes a picture is worth a thousand words as they do say. Who "they" are I have no idea but it might help us to understand what is happening.

It's been a long time since I've used WMP and I thought that it might present a thumbnail of the video in it's library view.

The other part of my question referred to the way you use Windows Explorer. Libraries are a bit different from folders.

If you open the Videos Library in the left hand navigation pane, what gets presented.

If you open the My Videos folder under your user profile, what gets presented?

MohavePc asked for a snap shot, could you post a shot of My Videos folder and one of the Videos Library?

Theres nothing wrong with the default program thing, its all set to WMP, i tried using the reg files you linked and it did nothing.

Heres what i mean btw :

And its for every single video file, not just .mp4.
