Okay, this is admittedly not useful for anything; it’s just eye candy. But if you’d like to change the thumbnail preview pictures in Windows Explorer so that they look like snippets of film, with the little sprocket holes along the sides, it’s sort of cool. Here’s how:
- As always, back up the registry before making changes.
- Open the registry editor and navigate to the following key: HKEY_CLASSES_ROOT \ SystemFileAssociations \ image
- In the right details pane, right click Treatment and select Modify. vIn the Edit DWORD (32-bit) Value dialog box, change the hexadecimal value in the Value Data field to 3 (the default is 2).
- Close the registry editor and reboot the computer.
