Thumbnails Missing in Vista Explorer Large & Extra Large View

Question

I've noticed that thumbnail images are missing in the Vista explorer (View > Large/Extra Large Icon). I used to see a preview image in the explorer window without having to launch Acrobat Reader version 7.xxxx. I never use the preview pane, it was never necessary when the thumbnails provided a quick look inside the PDF document.
However, after installing version 8.1.1, these thumbnail images have disappeared and are now replaced by the generic Acrobat icon which came with the latest version. What's with that??? Do we HAVE TO upgrade from the free reader version to the pay version to get these previews?
This is not a Vista problem! This happened just after installing Reader 8. Images such as bitmaps, Photoshop psd files, png's, video mpg's, mpeg's and wmv's, for example, all display thumbnail images of the content in a Vista explorer folder window. But the PDF files only show the generic icon.
