2. Now go to:

HKEY_CLASSES_ROOT\SystemFileAssociations\video (to customize border for videos)

3. In right-side pane, look for a DWORD value "Treatment". It would be set to 2 for images and 3 for videos by default. Double-click on it and set its value to any of following:

0 - To remove the border (Makes thumbnail preview a little bit faster)
1 - To add drop-shadow effect
2 - To add photo-shadow effect
