shortcut icon problems

I can't find help anywhere for this..After my Windows updates, my computer re-starts, and when it comes back on, almost all of my personal set icons change to the generic icon, ( a page of paper with a box containing 9 colored dots in the center)..When I right click on properties, to restore my original icon, it won't accept it..It will only accept a new icon that wasn't used before..??..!! this has happened 3-4 diff times, all after updates...?????
