I accidentally came across a slightly easier fix for this bug. Instead of setting "Turn off the display of thumbnails and only display icons on network folders" to Enable, I simply changed the Windows Explorer display setting from "Details" to "Content". Then I was able to delete my Thumbs.db files without any complaints from Windows 7, even though I have thumbnails enabled. After deleting the offending file(s), I just restore the display to "Details" again.
