Thumbnails for video files in Windows 7 contain a film strip overlay on the sides which consumes part of the thumbnail image. If you need to remove the video sprockets / film strip effect, there is a registry setting you need to change.

Click Start, type regedit.exe and press {ENTER}

Navigate to the following key:


In the right-pane, double-click Treatment and set its value data to 0.

Here are the possible values…

0No Adornment
1Drop Shadow
2Photo Border
3Video Sprockets

For more details, refer to section "Thumbnail Adornments" in this MSDN documentation.

Exit the Registry Editor.

Logoff and log back in to your account. Filmstrips are now gone!

    This worked on windows vista too. I did not need to log out/in. The change happened as soon as I closed the popup dialogue double clicking treatment gave.

    Cool. Wish there was a way to change the horrible angled folder thumbnails back to the XP style flat previews.

    Thanks for this bit of information. Now I know how to put them back.
