Uncheck Save Taskbar Thumbnail Preview.
That's unfortunately only a space saving option. It only disables the saving of the thumbnail picture for a quicker preview next time round.
Nice thought though.
@lt200420, did you restart your pc after changing the registry? Also, as far as we can tell there is no way to disable the thumbnails other than using a basic theme, or disabling transparency.
