Using Windows 7 RTM Ultimate x64, (2) Nvidia 250 GTS SLI. I always dump PDF's and docs on my desktop. I use the large icons. At first the thumbnails worked perfectly for PDF's and Docs, as they did in Vista..... nice large thumbnails of the PDF's and documents. Initially they didn't show up... but after a couple of reboots... they were there. After two days, they are all gone again. Oddly, my JPG's still show their thumbnails.
I have absolutely no idea what changed. I have tried all the settings I can find and they seem to be correct (especially since my JPG's display). Yes, I have added programs and tweaked a few things, but nothing that should have affected the thumbnails. I am using the latest Nvidia driver
(190.56). I have a couple other Windows 7 machines and they also seem to afflicted with the issue.
Any suggestions would be appreciated! I need my thumbnails back
