I have lost my windows preview thumbnails and have tried everything in this forum to get them back. In my taskbar properties, it is unchecked and NOT hilighted to recheck it. Can someone help me out here.

Another issue might be that you have changed the program that handles images.

To fix that, right-click on an image and select Open With - > Choose Program.

From the program list choose "Windows Picture and Fax Viewer" and check the box below "Always use this program to open files of this type" (or something, I have it in greek on mine) and press OK.

Every now and then, when I download a new image file, its thumbnail would not appear when I view it in Explorer. Instead of the thumbnail image, it would display a generic icon.

It would only appear after I reboot the computer.

I am not sure if this is related to your issue but there is a known issue with Vista 64 and the thumbs created by 32 bit applications like Abobe Acrobat. You can find information about this problem and a suggested work around is to use the 32 bit Windows Explorer. You can find the information here:

Some Windows Explorer extensions and some Control Panel items are not displayed on computers that are running an x64-based version of Windows
