Some time ago, I discovered that almost all of my 85 desktop shortcut icons had changed to a default symbol. Only 13 have other than the default picture, and most of these are folder shortcuts, or PDF file shortcuts. I do not recall what action on my part might have triggered this event. I have already conducted a reinstall-"repair" operation for Vista Home Premium x64 system, but this did not resolve the problem. Can anyone suggest how to recover the original stylized icons for these "lost" shortcut icons?
