I have a fresh Windows 8 machine which I just unwrapped, but after moving all of my files to a NAS box I have lost all thumbnails in explorer. I browse to the folder and all my JPEGs just have a standard icon. How can I get explorer to show the thumbnails?
After much research I have found the one solution that seems to make a difference on my Windows 8 system, and that is:
Create the following registry key:
(DWORD 32) : DisableThumbnailsOnNetworkFolders : Value = 0
Once this was set and the system rebooted, explorer is now merrily making thumbnails for folders resident on network drives.
