[FIX] Thumbnails / Pictures not showing in Windows 7 or Vista
So your small preview thumbnail pictures that normally show up have disappeared huh?
Well its hard to say why they did so but some how the option to display them was disabled so we simply need to re-enable it to get the thumbnails back.
Simply follow the below instructions and you should be sitting pretty:
1. Open the Start Menu.
2. Click on the Control Panel button on the right. (see screenshot below)![]()
3. Open Visual Effects settings. (See screensho below)
4. To Turn On Thumbnails A) Check Show thumbnails instead of icons, then click on OK.
